DIFFERENTIAL OFFSET CALIBRATION CIRCUIT |
摘要 |
A differential offset circuit adapted for an adaptive filter of a receiver front end is provided. The differential offset circuit includes four controllable current sources which are respectively coupled to two differential output terminals of the adaptive filter. The current magnitudes of the controllable current sources are capable of being adjusted according to design requirements so that the differential offset of the adaptive filter is mitigated to avoid that the adaptive filter outputs a distorted signal to affect the accuracy of signal transmission.
