... In this model, transistors Q1, Q2, and Q3, V1, and OA1 form the current mode rectifier. During the positive half cycle, the output of OA1 (through V1) turns Q1 “on”, and the current through this transistor servo’s the inverting input of OA1 to ground. This feedback current is mirrored by Q2, and dra ...
