The present invention is a voltage regulator circuit with enhanced
frequency compensation. The voltage regulator includes an error
amplifier, a dynamic bias circuit, an enhanced frequency compensation
unit, a pass device and a compensation circuit. A signal from the pass
device acts as an input signal of the error amplifier and is compared
with another input signal, producing a differential signal. The
differential signal is amplified and then provided to the dynamic circuit
and the enhanced frequency compensation unit. The enhanced frequency
compensation unit is provided such that a zero reference value in a
left-hand plane can be generated to optimize the compensation for the
voltage regulator circuit. The error amplifier includes a capacitor for
compensating an output voltage of the voltage regulator circuit.
