  • ULTRA-LOW ENERGY PER CYCLE OSCILLATOR TOPOLOGY
    Publication number: 20220294426
    Abstract: In described examples of an integrated circuit (IC), an oscillator includes Schmitt trigger delay cells connected in a ring topology. The Schmitt trigger delay cells have a high input threshold approximately equal to Vdd and a low input threshold approximately equal to Vss to increase delay through each cell. An output buffer receives a phase signal from an output terminal of one of the Schmitt trigger delay cells and converts a transition phase signal to a faster transition clock signal. The output buffer has control circuitry that generates non-overlapping control signals in response to the phase signal, to control an output stage to generate the fast transition clock signal while preventing short circuit current in the output stage.
