   v0  P/N=2
   v1 P/N=1.5
   v2 P/N=2.25
   v3 P/N=1
   v4 P/N=4
   v5 P/N=2.6

Inverters with different drive strengths and P/N ratios.
The P/N ratios used for each version are shown to the right. The P:N ratio of 2 offers good output skew and speed, while 1.5 is close to the fastest speed. 2.25 is a balanced ratio if the mobility ratio µ equals 2.25 and 2.6 is balanced for this techno where µ is close to 2.6. P/N ratios of 1 and 4 give heavily skewed outputs for specific applications.
The v6, v7 and v8 versions are experimental cells. The iv1v2x2 is considered as the reference inverter for logical effort calculations.
