In combinatorial blocks of static CMOS circuits transistor sizing can be applied for delay balancing in order to guarantee synchronously arriving signal slopes at the input of logic gates. Since the delay of a logic gate depends directly on transistor sizes, the variation of channel-widths and -...
Transistor Sizing in VLSI Design Using the Linear Delay Model November 16, 2020 by Tosin Jemilehin In this article, we will learn how to find the optimal size of a transistor/logic gate present in a larger circuit to provide the desired performance using the linear delay model. In...
While an absolute marvel of engineering, the ES/9000 was essentially a flop, and by 1997 IBM too would move fully to CMOS transistor technology. Over the years we’ve featured a lot of [Ken]’s work, perhaps you’d like to know more about his techniques. Posted in hardware, Retro...
1 and the ensuing buffer chain, a load reduction in the inverter driving node A4 reflects into a reduction in the inverter driving node A3, and in turn allows for a smaller NAND sizing to begin with. Besides optimizing jitter, the present invention thus enables a lower power consumption for...

The existing CMOS technology faces numerous critical issues in terms of high power dissipation, short channel effects, and reduced gate control when scaled to nanoscale dimensions. These reliability issues have the tendency to significantly degrade the system performance in the near future. The significa...

An implemented 32-b adder using complementary CMOS has a power-delay product of less than half that of the CPL version. Robustness with respect to voltage scaling and transistor sizing, as well as generality and ease-of-use, are additional advantages of CMOS logic gates, especially when cell-...
Proper device sizing and especially adjusting the size relationship between complementary transistors provides considerable performance benefits. The iFET, being a compound structure, offers extensive opportunity to establish impedance matching and gain control through proper ratio of the physical device ...
