Write channel having a preamplifier and a non-uniform transmission line

摘要

A high-speed transmission circuit includes an inductive head. The high-speed transmission circuit also includes a non-uniform transmission line having a variable characteristic impedance. The non-uniform transmission line is coupled between the inductive head and an endpoint node such that pulses are conducted over the non-uniform transmission line. The variable characteristic impedance is greater near the inductive head than near the endpoint node.
