Abstract: In some examples, a circuit includes a capacitor having a first terminal and a second terminal, the first terminal coupled to a voltage supply terminal of the circuit. The circuit also includes a transistor having a transistor gate, a transistor drain, and a transistor source, the transistor source coupled to ground and the transistor drain coupled to an input terminal of the circuit. The transistor is configured to conduct responsive to a gate signal received at the transistor gate, the gate signal based on a signal provided at the second terminal of the capacitor. The circuit also includes a Schmitt trigger having a Schmitt trigger input coupled to the transistor drain.
