Abstract
Briefly, in accordance with one embodiment of the invention, a calibration circuit may detect a difference between first and second outputs of a differential output programmable gain amplifier to determine a dc offset at the differential output. In the event an offset is detected, a differential gain of the programmable gain amplifier may be adjusted until the offset is adjusted, or eliminated, to an acceptable predetermined value.
