delay on cmos inverter while increasing W of nMOS and pMOS

Nettet28. apr. 2014 · We have one CMOS inverter and a fixed capacitance as load , for example 0.1pF . As an experiment we increase W of nMOS and pMOS and each time we increase W, we find the delay of the inverter (using spice). We notice that while increasing W, the rate of decreasing delay is dropped. Why is this happening ? Nettet18. jan. 2010 · in lots of papers,they combine a NAND2 following by a chain of cmos inverters for delay.but when i was simulating,i found that the delay of inverter chain is very small and it is not adequate. it is, however,still small when i add more inverters. anyone have good idea for less inverter and large delay? how to design the delay inverter? thx! NettetFor example: at 25C & 5V, a 74HC04 has a typical propagation delay of 7ns, and a 74HC157 has 11-12ns. Decreasing the voltage would increase the delay. By changing to 74LVC technology and decreasing the power supply to 3.3V, you can get a 74LVC04 with a typical delay of 2ns, or a 74LVC157A with a delay of 2.5-2.7ns. data and insights analyst salary
