Abstract
A differential signal offset adjustment circuit may include a first circuit for receiving a first one of a differential input signal and generating a first one of a differential output signal with positive offset based on a differential offset signal. The circuit may further include a second circuit for receiving a second one of a differential input signal and generating a second one of a differential output signal with a negative offset based on the differential offset signal.
Claims20
A differential signal offset adjustment circuit, comprising:
- a first circuit for receiving a first one of a differential input signal including a DC offset and generating a first one of a differential output signal with a positive offset based on a combination of a differential offset signal and the DC offset;
- and
- a second circuit for receiving a second one of the differential input signal including the DC offset and generating a second one of the differential output signal with a negative offset based on a combination of the differential offset signal and the DC offset.
A method, comprising:
- receiving a first one of a differential input signal including a DC offset at a first circuit;
- generating a first one of a differential output signal with a positive offset voltage based on a combination of a differential offset signal and the DC offset;
- receiving a second one of the differential input signal including the DC offset at a second circuit;
- and
- generating a second one of the differential output signal with a negative offset voltage based on a combination of the differential offset signal and the DC offset.
