Abstract
A differential correlator for a receiver including a voltage controlled current source which is controlled by an input data signal which is based on a received signal. A switching circuit selectively couples the controlled current to one of two storage capacitors as a function of a reference signal. A comparison circuit compares the integrated voltages on the storage capacitors at the end of each integration period T to provide user data as a function of the comparison. A discharge circuit discharges the storage capacitors to a common initial voltage after the integrated voltages are compared.
