    摘要: A measurement instrument for measuring electrical characteristics of a device under test (DUT) includes a synchronization signal generator for generating a synchronization signal transmittable to a receiver, a voltage controlled phase shifter (VCPS) connected with the synchronization signal generator and a phase-to-voltage converter configured to drive the VCPS. The synchronization signal is transmitted via a duplexer configured to transmit the synchronization signal from the measurement instrument to the receiver via a fiber optic cable and retransmit the received synchronization signal from the receiver to the measurement instrument via the fiber optic cable. The phase-to-voltage converter receives as inputs the synchronization signal input to the VCPS, the synchronization signal output from the VCPS and the retransmitted synchronization signal received at the measurement instrument from the receiver. An output of the phase-to-voltage converter is provided as input to the VCPS.

    摘要: De-embedding apparatus and methods of de-embedding are disclosed. A de-embedding apparatus includes a test structure including a device-under-test (DUT) embedded in the test structure, and a plurality of dummy test structures including an open dummy structure, a distributed open dummy structure, and a short dummy structure. The distributed open dummy structure may include a first signal transmission line coupled to a left signal test pad and a second signal transmission line coupled to a right signal test pad, the first and second signal transmission lines having a smaller total length than a total length of signal transmission lines of the open dummy structure, and intrinsic transmission characteristics of the DUT can be derived from transmission parameters of the dummy test structures and the test structure.

    摘要: Systems and methods for sensing voltage on a chip are described herein. In one embodiment, a voltage sensor comprises a voltage-controlled oscillator coupled to a voltage being sensed, and a plurality of transition detectors, wherein each of the transition detectors is coupled to a different location on the oscillator, and wherein each of the transition detectors is configured to count a number of transitions at the respective location over a time period. The voltage sensor also comprises an adder configured to add the numbers of transitions from the transition detectors to generate an output value that is approximately proportional to the voltage.

    摘要: An electrosurgical generator includes primary and test sources. The primary source supplies a primary signal and the test source supplies a test signal. The electrosurgical generator includes an output circuit and an abnormality detection circuit. The output circuit is electrically coupled to the primary and test sources. The output circuit receives the primary and test signals from the primary and test sources, respectively. The output circuit is electrically coupled to a load to supply the primary signal thereto. The abnormality detection circuit is electrically coupled to the output circuit to detect an abnormality therein as a function of the test signal. The abnormality detection circuit can also determine a location of the abnormality within the output circuit.
