ABSTRACT:
A passive matching network is connected to an input/output line for an automatic test equipment drive channel to compensate for capacitances associated with a receiver circuit connected to the line, and also an optional current-mode driver circuit. The matching circuit preferably comprises a T-coil circuit that can include a bridging capacitor; separate T-coil circuits can be provided to separately compensate for receiver circuit and current-mode driver circuit capacitances. The driver and receiver circuits can be implemented on a common layer of an integrated circuit, with the T-coil windings implemented in a separate layer of the same integrated circuit that is spaced from the common layer by at least one dielectric layer.
