ABSTRACT:
An output stage (418) for an operational amplifier (403) powered by a first supply voltage rail (102) and a second supply voltage rail (104) includes a buffer (100) and a current booster (500) for amplifying an input voltage (105) into a low impedance output signal (117 and 520). The buffer (100) amplifies the input voltage (105) into the amplified output signal (117 and 520) when the input voltage (105) is within a buffer voltage range (210), the buffer voltage range (210) contained within a maximum voltage range (208) defined by a voltage difference in the first supply voltage rail (102) and the second supply voltage rail (104). The current booster (500) assists the buffer (100) in amplifying the input voltage (105) into the output signal (117 and 520) when the input voltage (105) is outside of the buffer voltage range (210) but within the maximum voltage range (208).
