Abstract
An integrated circuit includes a positive power supply node, a current tracking circuit, and a current mirroring circuit including a plurality of current paths coupled in parallel. The currents of the plurality of current paths mirror a current of the current tracking circuit. The current mirroring circuit is configured to turn off the plurality of current paths one-by-one in response to a reduction in a positive power supply voltage on the positive power supply node. The integrated circuit further includes a charging node receiving a summation current of the plurality of current paths, wherein a voltage on the charging node is configured to increase through a charging of the summation current.
