Claim Text:
1. A biasing circuit, comprising: an output terminal; a biasing terminal configured to receive from a voltage-booster stage a boosted voltage for biasing the output terminal; a filter coupled between the biasing terminal and said output terminal, and configured to filter disturbances on said boosted voltage; a switch configured to provide a current path between said biasing terminal and said output terminal when the switch is closed and allow the filter to filter the disturbances when the switch is open, the switch having a control terminal; and a control stage having an output terminal electrically coupled to the control terminal of the switch, the control stage being configured to close the switch by providing a control signal from the output terminal of the control stage to the switch, wherein the control stage includes a first input terminal configured to receive said boosted voltage and a second input terminal configured to receive a timing signal, and the control stage is configured to supply said control signal based on the boosted voltage and the timing signal.
