Claim Text:
1. A full-wave rectifier circuit for detection of differential input signals and common mode signal rejection, comprising: a first differential input circuit having a pair of first field effect transistors (FETs) of different conductivity type, each first FET having a control gate coupled to a respective differential input, one of said pair of first FETs having a drain coupled to an output node; and a second differential input circuit having a pair of second FETs of different conductivity type, each second FET having a control gate coupled to one of the differential inputs corresponding to the differential input coupled to said control gate of one of said first FETs of opposite conductivity type, one of said pair of second FETs having a drain coupled to said output node; where said pair of first FETs are coupled together for passing a first signal current therethrough responsive to a differential signal of a first polarity being input to said control gates of said pair of first FETs and said pair of second FETs are coupled together for passing a second signal current therethrough responsive to a differential signal of a second polarity being input to said control gates of said pair of second FETs.
