ABSTRACT:
A carrier current receiver employs a comparator driven differentially to square a received data signal. The same drive signal is applied to a sample and hold circuit in which a capacitor is charged to a level that is related to the data signal offset. A voltage-to-current converter responds to the capacitor charge and feeds a current to the input where it acts to correct the offset.
