Abstract

A frequency divider circuit is disclosed that generates output signals having a frequency substantially half of the frequency of the input signal. The circuit comprises two D-Flip-Flop circuits wherein one employs the said input signal and the other one employs the complement of the said input signal, and each of the two D-Flip-Flop circuits consists of a pair of loading transistors, two regenerative pairs coupled with each others, and two common-gate switches.
