ABSTRACT:
An amplifier circuit receives biasing during power-up to reduce propagation delay. A start-up circuit generates first and second control signals upon detecting the power supply potential to the amplifier below a predetermined threshold. The control signals enable a biasing circuit to establish a bias potential at the input of the amplifier. After the power supply potential reaches the predetermined threshold, the control signals from the start-up circuit change state to disable the biasing circuit and allow the amplifier to operate normally.
