Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 14:
15. A voltage regulator comprising:
a differential amplifier;
a pass transistor connected to an external load and an input of the differential amplifier;
a capacitor array connected between the differential amplifier and the pass transistor the capacitor array including a plurality of capacitors; and
a trimmer circuit connected to the capacitor array, wherein the trimmer circuit is
configured to engage and disengage the plurality of capacitors in the capacitor array according to process, temperature, and voltage (PVT) variations, and wherein the trimmer circuit includes:
a decoder; and
a switch array including a plurality of switches, wherein the switches include AND gates, wherein a first input of each of the plurality of switches in the switch array is coupled to receive a same load-dependent first input signal and a second input of each of the plurality of switches in the switch array is coupled to the decoder to receive a corresponding second input signal, and wherein an output of each of the plurality of switches in the switch array is coupled to a respective capacitor in the capacitor array.
