Claim 4:
5. The amplifier circuit of claim 2, wherein:
the first half output chopper circuit comprises:
a first switch coupled between the first output voltage terminal of the amplifier circuit and the output of the first transistor of the transistor pair, the first switch configured to close when the control signal has a first value and open when the control signal has a second value, and
a second switch coupled between the second output voltage terminal of the amplifier circuit and the output of the first transistor of the transistor pair, the second switch configured to close when the control signal has the second value and open when the control signal has the first value; and

the second half output chopper circuit comprises:
a third switch coupled between the first output voltage terminal of the amplifier circuit and the output of the second transistor of the transistor pair, the third switch configured to close when the control signal has the first value and open when the control signal has the second value, and
a fourth switch coupled between the second output voltage terminal of the amplifier circuit and the output of the second transistor of the transistor pair, the fourth switch configured to close when the control signal has the second value and open when the control signal has the first value.
