Abstract
A start-up circuit for a self-biasing generator provides a reference voltage or a reference current, the start-up circuit including an impedance circuit. In response to a start-up signal input to the start-up circuit, the impedance circuit is coupled to a bias voltage line of a current mirror circuit of the self-biasing generator, thereby inducing current to flow in the self-biasing generator and starting the self-biasing generator. A bypass current source is coupled to the current mirror circuit and to the impedance. The bypass current source is configured to be driven by a current in the current mirror circuit and to supply current to the impedance in proportion to the current in the current mirror circuit, thereby limiting the current induced to the self-biasing generator by the start-up circuit.
