ABSTRACT:
A voltage regulator comprising two feedback loops for regulating a load voltage, where the first feedback loop comprises a pass transistor to source current to the load, and the second feedback loop comprises a shunt transistor to shunt current from the pass transistor to ground. The use of two feedback loops allows the design of a voltage regulator in which it small-signal impedance, as seen by a power rail, has a phase not less than −90 degrees. This mitigates interactions between the power rail and the voltage regulator that may lead to oscillations, without the need for a relatively large de-coupling capacitor. Other embodiments are described and claimed.
