PROTECTION CIRCUITRY AND METHODS FOR AUDIO GROUND CIRCUITS

Self-grounded circuitry (10) includes a signal channel conducting an output voltage (VOUT1). A charge pump (2) powered by a reference voltage (VDD) produces a control voltage (VCP). The control signal is at a low level if the reference voltage is low and is boosted to a high level if the reference v...
