Amplification circuitry is disclosed that couples neutralization transistors to amplification transistors to neutralize parasitic capacitance of the amplification transistors. Gates of a first amplification transistor and a first neutralization transistor are coupled together, and gates of a second amplification transistor and a second neutralization transistor are also coupled together. Drains of the first amplification transistor and the second neutralization transistor are coupled together, and drains of the second amplification transistor and the first neutralization transistor are also coupled together. Sources of neutralization transistors are coupled together at a node, such that a voltage swing of a first signal in the first neutralization transistor may be canceled by a voltage swing of a second signal in the second neutralization transistor. The node also couples to a resistor that prevents charge building in the neutralization transistors.

An amplifier includes first and second input transistors, a first current mirror, a second current mirror, and a third current mirror. An input terminal of the first current mirror is coupled to a drain of the first input transistor, an input terminal of the second current mirror is coupled to a drain of the second input transistor, and an input terminal of the third current mirror is coupled to an output terminal of the first current mirror. An output terminal of the first current mirror and an output terminal of the third current mirror are coupled to an output of the amplifier. The amplifier also includes third and fourth input transistors, wherein a drain of the third input transistor is coupled to the input terminal of the third current mirror, and a drain of the fourth input transistor is coupled to the output of the amplifier.
