ABSTRACT:
A constant phase limiter is disclosed utilizing cascaded RC coupled amplifiers with complex feedback. In the illustrative embodiment, five NPN transistors connected in a common emitter configuration are cascaded. The first stage is a signal conditioning amplifier for setting the limiting threshold. By harmoniously selecting the operating conditions for each of the other stages, an overall constant phase/limited output characteristic can be achieved for the desired range of input signal.
