Abstract:
A noise filtering circuit, a digital to analog converter and an electronic device are provided. The noise filtering circuit comprises a first amplifier configured to receive a bias voltage at a first input terminal, receive a bias output voltage at a second input terminal though a feedback path, and compensate for a difference between the bias voltage and the bias output voltage; a first transistor connected to an output of the first amplifier and having a gate to which an off-voltage is applied; a first capacitor connected to the first transistor; a second capacitor connected to the output of the first amplifier; a second transistor connected to the second capacitor and having a gate to which an off-voltage is applied, and a second amplifier having an input terminal connected to the first capacitor and a second input terminal connected to the second transistor.
