Claim 23:
24. The electronic device of claim 23, wherein:
the input chopper circuit comprises:
a first half input chopper circuit coupled to an input of the first transistor of the transistor pair, the first half input chopper circuit configured to selectively couple the input of the first transistor to the first input terminal of the amplifier circuit or the second input terminal of the amplifier circuit based on the value of the control signal, and
a second half input chopper circuit coupled to the second transistor of the transistor pair, the second half input chopper circuit configured to selectively couple the input of the second transistor to the first input terminal of the amplifier circuit or the second input terminal of the amplifier circuit based on the value of the control signal; and

the output chopper circuit comprises:
a first half output chopper circuit coupled to an output of the first transistor of the transistor pair, the first half output chopper circuit configured to selectively couple the output of the first transistor to the first output voltage terminal of the amplifier circuit or the second output voltage terminal of the amplifier circuit based on the value of the control signal, and
a second half output chopper circuit coupled to an output of the second transistor of the transistor pair, the second half output chopper circuit configured to selectively couple the output of the second transistor to the first output voltage terminal of the amplifier circuit or the second output voltage terminal of the amplifier circuit based on the value of the control signal.
