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 18):
An open circuit detector, comprising a first input node, a second input node, a difference amplifier and a signal generator providing a time varying signal for adjusting a common mode output voltage or a common mode input voltage of the amplifier, such that the input current becomes modulated in response to the reference signal, and a circuit for detecting when the common mode gain of the amplifier exceeds a threshold, the reference signal being applied to a node that sets a common mode output voltage of the amplifier or sets a common mode input voltage of the amplifier.
