Abstract
Aspects of the invention include a circuit having a two-stage amplifier coupled to a transistor array and to a comparator, the transistor array being configured to provide an output to a load, the transistor array including transistors. The circuit includes a controller coupled to the comparator and to the transistor array, the two-stage amplifier being configured to modulate a current density in the transistor array via gate terminals of the transistors, wherein, by using the comparator and the controller, the two-stage amplifier is configured to modulate a number of the transistors that are to couple to the load.
