ABSTRACT:
A phase canceller for a carrier recovery network (CRN) to cancel phase shifts associated with the band pass filter in the network. The canceller is a semiconductor device receiving an input signal at one junction to cause emitted carriers to migrate to a collector at a controlled rate determined by an applied electric field between a pair of ohmic contacts located between emitter and collector junctions with the field control by a signal from a phase detector in the AFC loop of the CRN.
