Abstract
A voltage holding circuit and an electronic device using thereof are provided. The voltage holding circuit includes a first transistor, a second transistor, and a first capacitor. A first terminal of the first transistor is coupled to an input voltage, and a control terminal of the first transistor receives a control signal. A first terminal of the second transistor is coupled to a second terminal of the first transistor, a second terminal of the second transistor is an output terminal of the voltage holding circuit, and a control terminal of the second transistor receives the control signal. A first terminal of the first capacitor is coupled to the second terminal of the first transistor and the first terminal of the second transistor. A holding voltage on the first terminal of the first capacitor is maintained by the first capacitor and parasitic diodes of the first transistor and the second transistor.
