Abstract
A balanced, differential, cross-coupled amplifier including an input stage for receiving a differential input and including an input transconductance differential pair and a feedback transconductance differential pair; and an output stage responsive to the input stage for providing a differential output; the differential input being connected to one input of the input transconductance differential pair and one input of the feedback transconductance differential pair, the differential output being fed back to one input of the input transconductance differential pair and one input of the feedback transconductance differential pair for balancing the currents in the transconductance differential pairs over the input range.
