Abstract
A voltage regulator includes a pass element having a control input coupled to a control node and operable to generate an output voltage at an output node, a negative feedback amplifier operable to receive a reference voltage and the output voltage and generate a signal at the control node based on a difference between the reference voltage and the output voltage, and a noise cancellation circuit coupled to the control node and the output node and operable to generate a bias current at the control node based on the output voltage.
