ABSTRACT:
A simple, low cost circuit with only passive components, and thus low power consumption, is provided for baseline restoration of an AC coupled signal. The circuit includes a passive network of diodes arranged in a star configuration and an RF-transformer. A differential signal strategy may be employed by including a differential amplifier at the input and output of the passive network.
