ABSTRACT:
A MOS current switching circuit comprises a first MOSFET, a second MOSFET, a first control circuit, a second control circuit, and an inverting amplifier. The inverting amplifier receives an output voltage of a current source to provide a feedback bias voltage to the first and second control circuit which are controlled by a control signal. The first and second control circuits are complementary operated to each other in response to the control signal to provide the feedback bias voltage to the gate electrode of the first or second MOSFET. The first or second MOSFET passes selectively a noiseless constant current from the current source toward the output terminal.
