This book was released on 1997 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-level decision feedback equalization (MDFE) is an effective technique to remove inter-symbol interference (ISI) from disk readback signals, which uses the simple architecture of decision feedback equalization. Parallelism which doubles the symbol rate can be realized by setting the first tap of the feedback filter to zero. A mixed-signal implementation has been chosen for the parallel MDFE, in which coefficients for the 9-tap feedback filter are adapted in the digital domain by 10-bit up/ down counters; 6-bit current mode D/A converters are used to convert digital coefficients to differential current signals which are summed with the forward equalizer (FE) output, and a flash A/D is used to make decisions and generate error signals for adaptation. In this thesis, a description of the parallel structure and the adaptation algorithm are presented with behavioral level verification. The circuit design and layout were carried out in HP 1.2um n-well CMOS process. The design of the high-speed counter and the current-mode D/A are discussed. HSPICE simulations show that a symbol rate of 100Mb/s for the feedback equalizer is readily achieved.

This book was released on 2024-01-31 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes machine learning-based new principles, methods of design and optimization of high-speed integrated circuits, included in one electronic system, which can exchange information between each other up to 128/256/512 Gbps speed. The efficiency of methods has been proven and is described on the examples of practical designs. This will enable readers to use them in similar electronic system designs. The author demonstrates newly developed principles and methods to accelerate communication between ICs, working in non-standard operating conditions, considering signal deviation compensation with linearity self-calibration. The observed circuit types also include but are not limited to mixed-signal, high performance heterogeneous integrated circuits as well as digital cores.

Download or read book Adaptive Decision Feedback Equalization With Continuous time Infinite Impulse Response Filters written by Shayan Shahramian and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In high-speed (10+Gb/s) chip-to-chip links, the primary impairments to signal integrity are noise, crosstalk, and a smooth tail in the pulse response resulting in inter-symbol interference (ISI) sometimes spanning more than 10 unit intervals (UIs). Although often simple in their implementation, continuous time linear equalizers amplify high-frequency noise and crosstalk and consume extra power. A conventional discrete-time (DT) decision feedback equalizer (DFE) is well-suited and power efficient for channels with a few dominant post-cursor ISI terms, however, the power can become prohibitive for channels with many post-cursor ISI terms. Infinite impulse response (IIR) DFEs can equalize post-cursor ISI persisting 10 or more UIs while consuming low-power comparable to just one DT tap. DFE architectures with varying numbers of DT and IIR taps are compared for use in typical wireline channels, and it is found that 2 IIR taps can offer an excellent compromise between power consumption and performance. However, an IIR DFEâ s performance degrades significantly as the feedback loop delay increases. Fortunately, adding a single DT tap can eliminate the degradation. The first ever hybrid DFE combining 1 DT and multiple (2) IIR taps is presented equalizing 24dB loss at half the bitrate while consuming 4.1mW at 10Gb/s. A novel edge based adaptation algorithm is also presented for DT DFEs which converges faster than previous algorithms while using the same high-speed circuitry and signals required for clock recovery. The edge based algorithm is extended to work for a 1 DT + 1 IIR DFE. The 1 DT + 1 IIR DFE along with integrated clock recovery and adaptation is demonstrated in 28nm FD-SOI CMOS. At 16Gb/s with a 30dB-loss channel, a BER below 10â 12 is measured over a 0.3UI timing window. The novel edge-based algorithm adapts both IIR and discrete-tap equalizer coefficients using the same high-speed circuitry and signals required for clock recovery. The adaptive DFE converges within 5us and is robust in the presence of poorly-conditioned data.
