Abstract
An apparatus having a first coupling network configured to receive an input voltage and output a first gate voltage and a second gate voltage at a first gate node and a second gate node, respectively; a stacked complementary common-source amplifier pair including a first common-source amplifier and a second common-source amplifier configured to receive the first gate voltage and the second gate voltage and output a first drain voltage and a second drain voltage at a first drain node and a second drain node, respectively; a second coupling network configured to provide a coupling between the first drain node and the second drain node to equalize the first drain voltage and the second drain voltage. A first inductor and second inductor couple the first and second drain nodes to a first and second DC node, respectively. Third and fourth inductors are coupled to the first and second inductor.
