A circuit comprises a reference voltage generating circuit, a first switch, a second switch, and a capacitive element. The reference voltage generating circuit has an input and output terminal for providing a reference voltage. The first switch has a first terminal coupled to a first power supply voltage terminal, a second terminal coupled to the input terminal of the reference voltage generating circuit, and a control terminal for receiving a first control signal. The second switch has a first terminal coupled to the output terminal of the reference voltage generating circuit, a second terminal, and a control terminal for receiving a second control signal. The capacitive element has a first plate electrode coupled to the second terminal of the second switch, and a second plate electrode coupled to a second power supply voltage terminal.
