Medical implant devices have been widely used in recent years. The Super-Regenerative Receiver has been on preferred architecture due to its power advantage over other architectures. We present a detailed analysis of the circuits and their equivalent models to be used in system level design of a Super-Regenerative Receiver in this paper. Designs were carried out in UMC 180nm process with a center frequency of 416MHz for MedRadio band. The study is concluded with the simulation results of the circuits and the equivalent models.
