Reducing the ever-growing leakage current is critical to high performance and power efficient designs. We present an in-depth study of high-level leakage modeling and reduction in the context of a full custom design environment. We propose a methodology to estimate the circuit area, minimum and maximum leakage current, and maximum power-up current, introduced by leakage reduction using sleep tr...

A high-speed fully differential current switch is presented. The clock-feedthrough effect is reduced by Swing-Reduced Drivers and neutralized by dummy transistors. With the use of Swing-Reduced Drivers (SRD), less charges are required to be transferred to/from the gates of the switching transistors, and hence, the switching speed can be increased without significant output error. The SRDs also ...

A silicon-based spin transistor of novel operating principle has been demonstrated in which the current gain at room temperature is 1.4 (n-type) and 0.97 (p-type). This high current gain was obtained from a hybrid metal/semiconductor analogue to the bipolar junction transistor which functions by tunnel-injecting carriers from a ferromagnetic emitter into a diffusion driven silicon base and then...

OVERVIEW: SOI (silicon on insulator) technology* has attracted a lot of attention as a promising breakthrough technology for high-speed, low-power LSIs. Research and development aimed at its practical use are now being conducted over a wide range of fields, including circuit design, device, process, and SOI wafer manufacturing. The key to the practical use of SIMOX (separation by implanted oxyg...

A high-performance CMOS unity-gain current amplifier is proposed. The solution adopts two feedback loops to reduce the input resistance and a nested-Miller technique to provide frequency compensation. A design example using a 0.8 mm process and a 2V supply is given and SPICE simulations show a bandwidth of 75MHz, no slew-rate limitations and a settling time better than 50 ns, irrespective of th...

In the 1970s Lawrence Berkeley Laboratory (LBL) was testing high current density magnets where EJ 2 limit up to two orders of magnitude higher than quench protection methods period would permit at time. LBL designing a (J) thin solenoid with large volume and stored energy (E). The accepted time ...
