Available in PDF, EPUB and Kindle. Book excerpt: The high power operation of the heterojunction bipolar transistor (HBT) has been analyzed by experimentally determining the junction temperature and separating temperature effects from other high power effects. In addition, an HBT large signal model has been developed that is valid for the linear, saturation, and cutoff regions, with low frequency temperature effects included. This model has been implemented in a commercial harmonic balance simulator, LIBRA from EEsof, making it particularly suitable for the design and simulation of HBT microwave power integrated circuits. In addition, an analysis of the most temperature-sensitive microwave elements for the HBT has been performed using measured s-parameter data at five elevated temperatures from 23 deg. C to 226 deg. C. The element values were compared to a physical model showing excellent agreement in magnitude and direction of change with temperature and bias. The transistor cutoff frequencies were also measured and calculated, showing a monotonic decrease with temperature of approximately 50% over the 200 deg. C range.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a study concerning the characterization of high frequency effectsin bipolar heterojunction transistors (HBT) in SiGe. During this work, the transistor of the BiCMOSB55 process (55nm) from STMicroelectronics was mainly analyzed. This state-of-the-arttechnology is characterized by a transition frequency of 320 GHz and a maximum oscillationfrequency (fMAX) of 370 GHz. The work is divided into three sub-themes, the objectives ofwhich are better characterization and better modeling of these components. The first part concernsthe extraction of fMAX from miniaturized transistors. Indeed, this fMAX frequency is afigure of merit of the first importance which is used to promote a technology. Unfortunately, it isobserved that the methodology used to extract fMAX by directly using Mason's gain formula onthe measured data gives very uncertain results on very advanced components. This complicatesthe analysis of transistor manufacturing batches. It has been shown that a simple small signalmodel extracted from the Y parameters removes the extraction uncertainties and allows the fineevaluation of a technology. The second part concerns the substrate of the transistor. In fact, thiszone of the transistor is the most important in terms of geometry, leading to distributed effects,the contribution of which is greater at high frequency. This therefore plays an essential role inthe modeling of the characteristics of the high frequency S parameters of modern HBT SiGe. Inthis work, we therefore extended and validated the transistor substrate model and we comparedthe SPICE-type simulations and measurements up to frequencies above 300 GHz. Finally, in athird part, we have oriented our modeling work towards the base, collector and emitter accessesas well as on the intrinsic transistor. Indeed, at very high frequency, that is to say above 100GHz for this technology, the transistor accesses must be modeled by distributed elements. Theintrinsic transistor is itself subject to so-called non-quasi-static effects. Sensitivity studies ofthe high frequency parameters of the HICUM model were carried out to establish a parameterextraction strategy. The high-frequency parameters are extracted with the support of the TCADsimulation and compared with S parameters measurements up to 500 GHz.

This book was released on 2015-10-14 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon-Germanium Heterojunction Bipolar Transistors (SiGe HBTs) are perfectly suited for high-speed electronics. Since the fabrication costs per design cycle are rapidly increasing with progressing frequency and complexity of the systems, accurate compact models are essential in order to enable robust circuit design. This thesis focuses on selected important physical effects in advanced SiGe HBTs, which have been either insufficiently modeled or completely missing in conventional compact models. New compact model equations for the transfer current were derived and successfully applied to a large set of different technologies. Hereby, the "Generalized Integral Charge Control Relation" was used as a foundation. A physics-based model utilizing small-signal parameters obtained from measurements is derived for modeling the current dependent collector charge. A brief chapter about substrate effects in bipolar transistors comprises the derivation of a compact model for the bias-dependent substrate resistance as well as a proper partitioning of the substrate capacitance. New extraction methods for compact model parameters are introduced and the application of existing methods to advanced processes is discussed. The derived joint extraction method for the emitter and thermal resistance as well as a scalable model for the transfer current have been successfully applied to experimental data of fast HBTs. The derived model equations were applied to a selected very advanced SiGe HBT process developed by IHP. Highly accurate models for DC- and small-signal as well as for large-signal characteristics are presented.

Nonplanar structures can be treated, response to transient conditions can be computed, and the high-frequency characteristics of transistors may be projected. The formulation of an electron energy balance equation is presented and included in the model in an attempt to more accurately compute high-field transport characteristics. The model is applied to some common design questions and experimental results are reproduced."

Available in PDF, EPUB and Kindle. Book excerpt: The importance of high frequency noise performance is increasing in advanced bipolar and complementary metal-oxide semiconductor (BiCMOS) technologies because of the high demands of radio frequency (RF) and mixed-signal integrated circuits used in the 5G communication, automatic-driving sensors and internet of things (IOT) applications. While the characterization and modeling of high frequency noise of BiCMOS transistors have been a topic for many years, some important issues have not been clarified. For example, the noise correlation is not well predicted for bipolar devices, the excess noise factor is not well understood for MOSFET devices and the temperature dependence of high frequency noise in BiCMOS devices is not well studied. Focused on these issues, this research establishes the approach to extract the noise transit time from the high current compact model (HICUM), demonstrates an efficient methodology for high frequency noise prediction for silicon-germanium heterojunction bipolar transistors (SiGe HBTs) and validates the prediction methodology over size, bias and temperature. One of the issues of high frequency noise modeling of bipolar transistors is the noise correlation effect. This research explores the physical origin of high frequency noise correlation, studies the noise model of SiGe HBTs and creates an approach to extract the noise transit time from the HICUM compact model. The extracted noise transit time is validated by the tuner-based noise measurement results of sample SiGe HBTs by comparing the four noise parameters between the calculated and measured data over transistor size, bias and temperature. The results show that the noise transit time can be independent of frequency but dependent on bias and temperature. Furthermore, a complete high frequency noise prediction system is established. Based on the extraction methodology of the noise transit time from the HICUM model, this dissertation demonstrates a low-cost and time-friendly methodology to predict the full high frequency noise properties of the bipolar devices directly from the S-parameter measurement, DC measurement and the parameters from the HICUM model without the tuner-based noise measurement. Compared with the conventional tuner-based noise measurement, this methodology can save the measurement time as well as achieve a good accuracy. For MOSFET devices, the importance of excess noise factor is increasing with the transistor size scaling down to sub-100nm for high frequency noise modeling, but it has not been well studied so far. This research analyzes the excess noise factor based on the device physics and characterization results, investigates the noise sources contribution and models the high frequency noise based on Y-parameter methodology.
