Abstract
Circuits and methods to achieve a clean start-up process and power saving of pulsed enabled electronic devices having an output capacitor and components requiring biasing during normal operating conditions are disclosed. These electronic devices could be e.g. LDOs, amplifiers or buffers. A set of switches are enabling bias currents from the output capacitor to internal nodes requiring biasing under normal operational conditions as e.g. output nodes of amplifying means.
