Abstract:
1. A circuit comprising: a filter; a first inverter having an input coupled to the filter; and a half-latch having a second inverter and a feedback circuit, wherein the second inverter is coupled in series with the first inverter and wherein the feedback circuit is coupled between an output of the first inverter and an output of the second inverter; wherein the feedback circuit includes a feedback transistor having a first terminal coupled to an output of the second inverter and a second terminal coupled to an output of the first inverter, wherein a drive strength of the feedback transistor is greater than a complementary transistor of the first inverter, and wherein the feedback transistor is configured to, when active, drive and maintain the output of the first inverter to a first state regardless of a state on the input of the first inverter.
