Abstract
An electronic circuit includes a differential amplifier, an output stage and a control circuit. The differential produces a signal proportional to a difference between a reference voltage and a voltage that is proportional to the output signal. The output stage includes multiple switchable circuits coupled between a voltage source and the output terminal such that the switching of the circuits changes impedance between the voltage source and the output terminal. The control circuit receives a feedback indicative of the voltage of the output signal and controls the impedance of the multiple switchable circuits such that current flowing out of the voltage source rises piecewise smoothly from power-on to steady state operation of the electronic circuit.
