A study of high-frequency regenerative frequency dividers

−−−− A comprehensive analytical study of high-frequency regenerative frequency dividers (RFD) is presented. The study includes two fundamental modes of operation in RFDs, namely stable and pulled operation modes. Differential equations characterizing the RFD behavior for both operation modes are derived. Next, an RFD circuit is designed and simulated in a 0.18µµµµm standard CMOS process. Simulations verify the accuracy of the proposed analytical models.
