PROTECTION CIRCUIT FOR EXTENDING HEADROOM WITH OFF-CHIP INDUCTORS

摘要

A protection circuit for extending the dynamic range of an amplifier circuit is described. Off-chip impedances, such as inductors, cause the output of the circuit to swing above and below the bias voltage. A protection circuit is included, either on chip or off-chip, to protect the integrated circuit components if there is a fault condition in either of the off-chip impedances.
