A fully differential class - A transconductance amplifier that maintains push-pull operation at its output over an increased common mode input range is described. Its improved slew rate, due to its push-pull nature, is ideal for driving heavy capacitive loads. This amplifier maintains its push-pull output feature over a wider power supply voltage range than other class-A push-pull architectures. Its gain and bandwidth are comparable to that of a single stage class-A folded cascade amplifier built in the same process and in the same area.
