Abstract: A circuit includes a first circuit module with a first input node, a second input node and an output node. The first circuit module receives an input signal at the first input node and generates an amplified signal at the output node. The circuit further includes a second circuit module coupled between the output node and a reference potential line. The second circuit selectively draws a current from the output node in response to a first control signal. The first control signal is generated in response to sensing a voltage fluctuation at a power supply node which supplies power to the first circuit module.

Abstract: A charge pump circuit includes a first power transistor selectively actuated by a first control signal to deliver relatively higher amounts of current to a capacitor and a second non-power transistor connected in parallel with the first power transistor and selectively actuated by a second control signal to deliver relatively lower amounts of current to the capacitor. The charge pump circuit includes a pumped voltage output that is sensed to generate a sensed voltage output. A comparison circuit compares the sensed voltage output to a threshold voltage. A logic circuit receives an output of the comparison circuit and enables the first power transistor and disables the second non-power transistor in a first mode of operation if the comparison is not satisfied. The logic circuit further disables the first power transistor and enables the second non-power transistor in a second mode of operation if the comparison is satisfied. The logic circuit returns from the second mode of operation to the first mode of operation after the comparison is subsequently not satisfied.
