Abstract: A fundamental building block of 2-level series-gated CML-based CMOS circuit which includes a number of inductive components for an electronic circuit system is disclosed that is capable of driving a significant level of external capacitive load at a high input clock frequency while providing a high level of output signal fidelity for optical data communication. The inductive components can be implemented as either separate inductors or as differentially coupled pairs forming a corresponding transformer element. The value of any particular inductive component is first selected to approximately resonate, at the desired output signal frequency, with its associated equivalent node capacitance but further adjusted to a final value that results in a minimum output waveform distortion for the particular application. Two exemplary cases of application, a Divide-by-2 counter and a Master Slave D-type Flip Flop are presented with associated time domain output waveforms.
