High bandwidth switched capacitor input receiver

Image Number 3 for United States Patent #6538502.

A differential amplifier has input and output terminals to generate a second signal at the output terminals for a first signal. The amplifier has feedback switches between the output terminals and the input terminals. Offset capacitors are coupled to the differential amplifier at the input terminals and reference voltages via charging switches to provide offsets for the first signal form the reference voltages via input switches.
