Abstract
An amplifier circuit comprising a power amplifier and a protection circuit coupled to the power amplifier. The protection circuit is configured to detect an overdrive condition and, in response to detecting an overdrive condition, apply a clamping status to the protection circuit to reduce a bias current to the power amplifier. The protection circuit has a capacitor and a recovery circuit including: a sensing component configured to monitor a change of charging and discharging currents to and from the capacitor respectively during the clamping status; a first device configured to set a time constant of the recovery circuit; and a second device configured to reset the protection circuit to remove the clamping status when the change of charging or discharging current is beyond a predetermined threshold.
