What is NMOS and PMOS in VLSI? Here, nMOS and pMOS transistors workas driver transistors; when one transistor is ON, other is OFF. ... When the input of nMOS is smaller than the threshold voltage (Vin< VTO,n), the nMOS is cut – off and pMOS is in linear region. So, the drain...
which is a simple logic gate that inverts the input signal. The CMOS inverter consists of a single PMOS transistor in the pull-up network and a single NMOS transistor in the pull-down network. When the input voltage is low, the PMOS transistor turns on and the NMOS transistor turns off,...

The optimum pMOS-to-nMOS width ratio is obtained and compared through three approaches: 1) finding the maximum current-over-capacitance ratio of a biased transistor; 2) deriving an analytical expression by minimizing the delay of an inverter; and 3) simulating different CMOS logic gates in the ...
We have designed an 8-bit CLA and inverter chain using 0.6 /spl mu/m CMOS technology and verified that NERL saves energy over ECRL by 2 to 3 times.doi:10.1109/GLSV.1999.757440Chulwoo KimSeung-Moon YooVLSI, 1999. Proceedings. Ninth Great Lakes Symposium on...
