Abstract:
A method includes using a pass device of a linear regulator to provide an output signal to an output of the linear regulator in response to a signal that is received at a control terminal of the pass device. The method includes using the linear regulator to regulate the signal received at the control terminal based at least in part on the output signal; and controlling a closed loop frequency response of the linear regulator to cause a direct current (DC) gain of the linear regulator to extend to a frequency near or at frequency of a zero that is associated with a decoupling capacitor that is coupled to the output of the linear regulator.
