This book was released on 2013 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complementary-Metal-Oxide-Semiconductor (CMOS) feature size scaling has resulted in significant improvements in the performance and energy efficiency of integrated circuits in the past 4 decades. However, in the last decade and for technology nodes below 90 nm, the scaling of threshold and supply voltages has slowed, as a result of subthreshold leakage, and power density has increased with each new technology node. This has forced a move toward multi-core architectures, but the energy efficiency benefits of parallelism are limited by the sub-thresahold leakage and the minimum energy point for a given function. Avoiding this roadblock requires an alternative device with more ideal switching characteristics. One promising class of such devices is the electro-statically actuated micro-electro-mechanical (MEM) relay which offers zero leakage current and abrupt turn-on behavior. Although a MEM relay is inherently slower than a CMOS transistor due to the mechanical movement, we have developed circuit design methodologies to mitigate this problem at the system level. This thesis explores such design optimization techniques and investigates the viability of MEM relays as an alternative switching technology for very-large scale integration (VLSI) applications. In the first part of this thesis, the feasibility of MEM relays for power management applications is discussed. Due to their negligibly low leakage, in certain applications, chips utilizing power gates built with MEM relays can achieve lower total energy than those built with CMOS transistors. A simple comparative analysis is presented and provides design guidelines and energy savings estimates as a function of technology parameters, and quantifies the further benefits of scaled relay designs. We also demonstrate a relay chip successfully power-gating a CMOS chip, and show a relay-based pulse generator suitable for self-timed operation. Going beyond power-gating applications, this work also describes circuit techniques and trade-offs for logic design with MEM-relays, focusing on multipliers which are commonly known as the most complex arithmetic units in a digital system. These techniques leverage the large disparity between mechanical and electrical time-constants of a relay, partitioning the logic into large, complex gates to minimize the effect of mechanical delay and improve circuit performance. At the component design level, innovations in compressor unit design minimize the required number of relays for each block and facilitate component cascading with no delay penalty. We analyze the area/energy/delay trade-offs vs. CMOS designs, for typical bit-widths, and show that scaled relays offer 10-20x lower energy per operation for moderate throughputs (

Download or read book BDD based Logic Synthesis of MEM Relay Circuits written by Mingzhe Jiang and published by . This book was released on 2013 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: As CMOS scaling begins to reach its fundamental limits, micro-electro-mechanical (MEM) relays provide an attractive option for improvements in energy efficiency due to their low leakage and nearly ideal I-V characteristics. However, mechanical actuation of MEM relays introduces significantly more delay than traditional CMOS electrical delay. In order to mitigate this effect, custom relay circuits are designed manually to make all mechanical actuations to happen simultaneously. A Karnaugh map-based synthesis tool was attempted to automate this design process. However, this synthesis tool has computational complexity growing exponentially in terms of the number of inputs, making it impractical for larger combinational circuit. Therefore, a synthesis algorithm based on binary decision diagram (BDD) has been investigated and developed in this work to conquer the computational complexity issue. Optimizations are performed at BDD level to reduce the number of devices needed in the design. In addition, circuits with multiple mechanical delays can also be generated by using BDD decomposition algorithm. The output is a relay netlist which can be ported to commercial place and route tools creating a simple automated MEM relay circuit design flow.

Download or read book Design Considerations for Nano Electromechanical Relay Circuits written by Matthew Edmund Spencer and published by . This book was released on 2015 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complementary metal oxide semiconductor (CMOS) technology has a minimum energy per operation, and that limitation is one of the myriad hurdles CMOS faces as it reaches small scales. This minimum energy is set by the balance between leakage energy and dynamic energy in subthreshold CMOS circuits, and sets floors on the achievable energy of digital units. A new, post-CMOS device with a sharper subthreshold slope than CMOS would be able to sidestep this minimum energy constraint. A candidate device called a nano-electromechancial (NEM) relay has recently emerged. NEM relays are small, integrated, capacitively-actuated, mechanical switches. The devices have demonstrated extremely high subthreshold slopes: ten orders of magnitude over a millivolt of swing. However, in the same lithographic process they are twenty times larger than a minimum sized CMOS device, their gate capacitance is ten times that of a minimum sized CMOS device, and their mechanical motion is an order of magnitude slower than a CMOS inverter. Can NEM relays improve digital systems even with these drawbacks? With proper circuit design, simulations say "yes". This dissertation examines three of the critical components of digital systems -- logic, timing, and memory -- and proposes NEM circuits which mitigate the weaknesses of the technology while achieving design goals. Simulations show that optimized relay logic, which arranges for all of the slow movement of relays to happen at the same time, can achieve an improvement of 10x in energy-per-operation below the CMOS minimum energy point at a penalty of 10x in delay and 3x in area. This logic style is experimentally demonstrated. In addition, relay latch based timing with staticization in the feedback path is simulated, which results in a working relay pipeline with zero mechanical delays of timing overhead. Finally, a new device called NEMory is proposed to build dense, non-volatile, mechanical memory. A hybrid NEMory/CMOS array is simulated, and its performance is compared to other memory solutions. The NEMory density is higher than any non-volatile memory except for multi-level cell, o-chip Flash, and its read and write energy are lower than any other non-volatile technology. Finally, the scaling and process limits of realizing mechanical devices are discussed in the context of future work.
