An amplifier comprises a common emitter stage coupled to a first and a second input, a common base stage coupled to the common emitter stage and to a first and a second output, and a cancellation path coupled to the common emitter stage and the common base stage and to the first and second outputs. The cancellation path generates a first cancellation signal that is 180 degrees out of phase with a first leakage signal at the first output and a second cancellation signal that is 180 degrees out of phase with a second leakage signal at the second output. The cancellation path comprises a first cancellation transistor coupled to the common emitter stage and the common base stage and to the first output and a second cancellation transistor coupled to the common emitter stage and the common base stage and to the second output.
