Abstract
A circuit for generating an output switching signal includes switching circuitry and comparison circuitry. The switching circuitry is configured to configured to discharge a first capacitive element in response to detecting a first phase of an input switching signal and connect the first capacitive element and a second capacitive element in parallel in response to detecting a second phase of the input switching signal. The comparison circuitry is configured to generate the output switching signal based on a voltage at the second capacitive element.
