Semiconductor circuit

A semiconductor circuit, comprising:

• a plurality of amplifiers, wherein
• each of the plurality of amplifiers is in a series connection, and
• the each of the plurality of amplifiers is configured to:
• receive a signal;
• amplify the received signal;
• and
• output the amplified signal;
• a first chopper switch connected to an input side of a first amplifier of the plurality of amplifiers;
• a second chopper switch connected to an output side of the first amplifier, wherein the first chopper switch and the second chopper switch are configured to act in synchronism with a first chopper clock;
• a third chopper switch connected to an input side of a second amplifier of the plurality of amplifiers;
• a fourth chopper switch connected to an output side of the second amplifier, wherein
• a position of the second amplifier is subsequent to a position of the first amplifier in the series connection,
• the third chopper switch and the fourth chopper switch are configured to act in synchronism with a second chopper clock, and
• the each of the first chopper switch, the second chopper switch, the third chopper switch, and the fourth chopper switch is configured to:
• switch between a first action to pass a plurality of differential input signals, and a second action to cross the plurality of differential input signals in synchronism with one of the first chopper clock or the second chopper clock;
• and
• output, as a plurality of differential output signals, one of the passed plurality of differential input signals or the crossed plurality of differential input signals;
• and
• a first phase compensation capacitor that includes a first end, wherein the first end of the first phase compensation capacitor is connected to a first differential input portion of the third chopper switch.
