Abstract:
It is often desirable to distinguish between an open circuit condition and a no signal condition. In both cases an input signal may be absent, but only one of these events represents a failure of the equipment. The present disclosure provides a way to use a difference amplifier to check for open circuit events, without requiring additional circuitry at the input of the amplifier.

Claim (Index 20):
A method of detecting channel imbalance in a circuit that comprises a difference amplifier, the method comprising modulating a common mode voltage at an output of the amplifier and monitoring a differential output voltage of the amplifier to identify changes in the differential output signal that are correlated with changes in the common mode output voltage, and to estimate channel imbalance as a function of a magnitude of the correlation.
