The authors present a new method of transistor sizing, in which the mathematical method is used for sizing of critical paths and the heuristic method is used for desizing of non-critical paths. The distributed RC delay model is used in the delay calculation, and the active transistor area is...
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...
Multi-threshold CMOS leads to about 10X leakage reduction in circuit standby mode. In this paper, we reduce leakage current through fine-grain sleep transistor (ST) insertion which makes it easier to guarantee circuit functionality at high speed and improves circuit noise margins [1]. We model ...
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-...
In this paper, circuit level analysis of the high frequency and low noise performance of an RF CMOS device with Leff=36 nm is performed using various layout schemes. By using the modeling methodology of interconnect metals and vias, it is found that the gate parasitic capacitance from the inte...
