Abstract
An amplifier circuit which, includes a first input for receiving a first input signal and a second input for receiving a second input signal. A first amplifier section is connected to the first input and the second input is present. The first amplifier section can combine the first signal and the second signal into a first combined signal, the first amplifier being connected to a first output, for outputting the first combined signal. A second amplifier section is connected to the first input and the second input, for combining the first signal and the second signal into a second combined signal, the second amplifier being connected to a second output, for outputting the second combined signal. A common mode section is connected to the first input and the second input, for generating a common mode signal based on a combination of the first signal and the second signal and outputting the common mode signal at a common output connected to the common mode amplifier. The first combined signal, the second combined signal and the common mode signal satisfy the condition that combining the first combined signal and the common mode signal results in a signal with an amplitude proportional to the amplitude of the first input signal and combining the second combined signal and the common mode signal results in a signal with an amplitude proportional to the amplitude of the second input signal.
