A tri-state chopper (TSC) circuit and method is disclosed. The tri-state chopper (TSC) circuit receives an input signal and a ternary signal and generates an output signal, wherein: the output signal tracks the input signal in both magnitude and sign when the ternary signal is in a first state; the output signal tracks the input signal in magnitude but has an opposite sign when the ternary signal is in a second state; and the output signal is set to zero when the ternary signal is in a third state.
