Patent abstract

An output stage for an amplifier is provided. The amplifier generally provides for compensation of an error current generated by the base-collector (or gate-drain) capacitance of a common base (or gate) amplifier transistor. The stage accomplishes this by utilizing a three transistor Wilson current mirror to combine the error current with a mirrored bias current to reduce the load current on the common base (or gate) amplifier transistor.
