Demodulator circuit for amplitude-modulated signals including diodes with like poles interconnected and a current source biasing the diodes in their forward conducting direction

摘要

A demodulation circuit for amplitude-modulated electrical signals includes at least two diodes having like poles interconnected with each other, the diodes being biased in their forward conducting direction such that the sum of the diode currents remains constant. The other poles of the diodes are connected to an input signal source of low impedance through a center tapped transformer winding or a choke coil.
