Abstract
The present disclosure provides for a clock distribution network for distributing clocking signals within a synchronous sequential logic circuit. The clock distribution network distributes the one or more clock signals by inductively and/or capacitively coupling a clocking signal from a primary distribution node to various secondary distribution nodes within the synchronous sequential logic circuit. The various secondary distribution nodes resonate at respective resonant frequencies to generate other clocking signals for use within the synchronous sequential logic circuit in response to receiving the clocking signal.
