摘要:
A variable amplifier with adjustable current to correct for DC offset. The variable amplifier includes a zero function, allowing for zeroing of some amplifiers in an amplifier chain during correction for DC offset of another amplifier in an amplifier chain. In some embodiments selectable current injection is provided to an amplifier chain in conjunction with signals from selectable mixers.
