nr2 standard cell family

 2-I/P NOR gate
nr2 symbol
The P/N ratio has been kept as close to 2 as possible for balanced output skew, even if this is not the fastest configuration.
z:(a+b)' cell width power Generic 0.13um typical timing (ps & ps/fF), pin b.
leakage dynamic tR=PropR+RampR×Load(fF), tF=PropF+RampF×Load(fF)
