ABSTRACT:
An amplifier stage or circuit for providing cross-point adjustment. The circuit may include a first input node configured to receive a first data signal and a second input node configured to receive a second data signal that is complementary of the first data signal. The circuit also includes a programmable first stage having a first node coupled to the first input node and a second node coupled to the second input node that is configured to adjust an amount of current provided to the first and second data signals to create a signal offset. The circuit further includes a second stage having a first node coupled to a third node of the programmable first stage and a second node coupled to a fourth node of the programmable first stage configured to provide the signal offset at a third and fourth node of the second stage to adjust the cross-point of the first and second signals.
