Abstract
A voltage regulator having bias current boosting is provided. The voltage regulator includes a power stage for providing an output voltage to a load. The voltage regulator includes a differential stage that receives a feedback voltage representative of the output voltage and a reference voltage and controls the power stage based on a difference between the reference voltage and the feedback voltage. The voltage regulator includes a bias current boosting stage that receives the feedback and reference voltages. The bias current boosting stage provides a boosted bias current having a current level that is based on the difference between the reference and feedback voltages. The boosted bias current biases the differential stage and hastens a response of the differential stage, in response to a change in the difference between the reference voltage and the feedback voltage, in controlling the power stage.
