While making transmission gate switch don't short source and body because in TG source and drain change according to the input and output values .

Random :

1. coupling capacitors act as short ciruit at all frequencies (as they have very high capacitance ) and open circuit at dc only .
2. To find out the current gain in cadence plot the output current and then only do the ac analysis .
 

SRAM design :

initial stored value 0.9 on both




 Write 1 operation then precharge and then read 1
