Abstract
A “floating” or “unipolar” DC supply is coupled to a filter comprising a pair of capacitors coupled in series across the supply output. Output voltages developed across the capacitors are applied to the supply inputs of an amplifier having an output coupled via a load to a common connection of the two capacitors. A bias supply, coupled in parallel with the filter, produces an output voltage representative of the relative values of the capacitor voltages which is fed back to an input of the amplifier via a threshold device. Under transient input signal conditions, which would tend to unbalance the filter capacitor voltages, the bias supply renders the threshold device conductive for diverting the transient from the amplifier input thus reducing the supply voltage imbalance and improving the transient recovery time of the amplifier.
