A voltage regulator, comprising an analog amplifier, a noise filter and a signal compensator, is disclosed. The noise filter for receives a first signal containing alternating current (AC) noise in which the noise filter substantially filters the AC noise from the first signal to thereby produce a second signal. The voltage regulator regulates the second signal to thereby generate a third signal therefrom. The third signal is substantially noise-free and is provided as a biasing voltage to the analog amplifier. The first signal is further provided to for amplification by the analog amplifier based on amplification characteristics of the analog amplifier and the amplification characteristics of the analog amplifier is determined by the biasing voltage provided to the analog amplifier.
