Abstract
An apparatus comprising an amplifier comprising at least one amplifier transistor, a threshold detection network and a bypass capacitor. The amplifier may be configured to generate an output signal at a collector in response to an input signal received at a base. The threshold detection network may be coupled between the collector and the base of the amplifier transistor. The threshold detection network may include a bias transistor having a collector coupled to the collector of the amplifier transistor and an emitter coupled to the base of the amplifier transistor. The threshold detection circuit may be configured to (i) sense a feedback current and (ii) provide a DC signal to the base of the amplifier transistor for dynamically sourcing bias current to the amplifier. The bypass capacitor may be coupled to the base of the bias transistor.
