A circuit includes a clock input node, a first signal input node configured to receive a first modulated signal switching between a first DC voltage and a second DC voltage, a bias circuit, a first output node, a first capacitor, a second capacitor, and switching circuitry coupled to the first capacitor and the second capacitor. Control circuitry is configured to initially set the switching circuitry in a first configuration in response to the first modulated signal having the second DC voltage, thereby charging the first capacitor to the second DC voltage and charging the second capacitor to the first DC voltage, and subsequently set the switching circuitry in a second configuration in response to an edge detected in the clock signal, thereby producing the first threshold voltage at the first output node after charge redistribution taking place between the first and second capacitors.
