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.

Abstract: An apparatus for conditioning an output waveform delivered from a testing device produces an output voltage that is the sum of a control voltage and an input voltage. To that end, the apparatus includes an input for receiving the input voltage, and an output capable of producing the output voltage. The output is coupled with the testing device. The apparatus further includes a voltage element coupled between the input and the output, and a switching element to alternatively charge and discharge the voltage element. The switching element controls the voltage element to change the control voltage between a first voltage and a second voltage. Consequently, the output voltage is the sum of the control voltage and the input voltage.

Abstract: A clamp for use with a circuit (having an output for delivering an output voltage) forms a voltage boundary for the output voltage based upon a clamp voltage. To that end, the clamp includes a clamp input for receiving the clamp voltage, a clamp transistor in communication with the clamp input, and a control transistor in communication with the output. The clamp also includes a driving source for driving at least one of the clamp and control transistors based upon the voltage at the clamp input and the voltage at the output. The output is clamped at a voltage within the voltage boundary of the clamp voltage after the clamp transistor begins being driven by the driving source.
