ABSTRACT:
A pair of PNP and a pair of NPN transistors are connected in a balanced self clamping circuit in which the output response is proportional to the product of transistor emitter current and differential base voltage. The circuit is linear and accurate for use in reading true (in-phase) power in an a-c circuit.
