Abstract
The circuit comprises an amplitude limiter made up with the use of two CMOS transistors and a circuit connected to the output of the amplitude limiter for filtering the signal and changing its level. The filtering and level-changing circuit is arranged, in particular, to achieve band-pass filtering in order to prevent aliasing effects which might arise during the sampling of the signal by subsequent switched-capacitance processing circuits, and to attenuate low-frequency components of the signal.
