Abstract
A wideband termination network includes a t-coil, a plurality of output transistors, and a first circuit. The first circuit includes a low-frequency termination resistor that presents a capacitance on a first node; a first inductor that isolates the capacitance on the first node from an output on a second node and that generates a pole-zero cancellation; a high-frequency termination resistor parallel to the first inductor; an adjustable capacitor configured to tune the capacitance on the first node to optimize the pole-zero cancellation; and a second inductor between the second node and a third node and that compensates for capacitance at the second node. The third node is provided between the first circuit and the t-coil.
