Amplifier circuit

An amplifier circuit comprising:

• an output terminal configured to output an amplification signal;
• an amplification unit comprising:
• a first transistor comprising a control terminal configured to receive a first input signal, a first terminal coupled to the output terminal and configured to output an amplified first input signal, and a second terminal;
• and
• a second transistor comprising a control terminal configured to receive a second input signal, a first terminal coupled to the output terminal and configured to output an amplified second input signal, and a second terminal;
• a first switch comprising a first terminal coupled to the second terminal of the first transistor, and a second terminal;
• and
• a second switch comprising a first terminal coupled to the output terminal, and a second terminal coupled to the first terminal of the first transistor or the first terminal of the second transistor;
• wherein the amplification signal is generated using at least the amplified first input signal and/or the amplified second input signal.
