ABSTRACT:
A PTAT biasing circuit for use in a bandgap referenced voltage source includes a startup sub-circuit. Prior to activation of a power up indication signal, the speedup circuit forces the PTAT biasing circuit from a degenerate operating point to a normal operating point. Upon detection of a feedback signal denoting the initiation of the PTAT biasing circuit, the startup sub-circuit terminates operation of the startup sub-circuit independent of the activation of the power up indication signal.
