cgi2ab standard cell family

carry generator inverting with 2 inverted inputs
cgi2ab symbol
The output is the inverted carry of carry input c and the inverse of inputs a and b. The stage efforts are 1.6, 1.9 and 2.4 for the x05, x1 and x2 drive strengths respectively. The cells here use a P/N ratio of about 2.
