Abstract:
A voltage regulator that includes a first amplifier, a second amplifier, a summer, and a transistor is presented. The first amplifier has a first gain and a first frequency bandwidth, and is configured to generate a first voltage output. The second amplifier has a second gain that is lower than the first gain and a second frequency bandwidth that is higher than the first frequency bandwidth, and is configured to generate a second voltage output. The summer is configured to generate a summed voltage output. The transistor is connected to the summer and configured to generate a regulated voltage based on the summed voltage output of the summer.
