  • Electric Current Measurement
    Publication number: 20110279133
    Abstract: A method for measuring electric current applied to a load includes: with a sensor element having an inaccuracy, measuring an electric current supplied to a load to produce a measurement of the electric current; with the sensor element, measuring the electric current with an added perturbation current; and using measurements of the electric current taken with and without the perturbation current to refine the measurement of the electric current.

  • Current mode pipelined analog-to-digital converter
    Patent number: 7839318
    Abstract: A pipelined analog-to-digital converter includes a plurality of stages each including a sample-and-hold circuit configured to output an analog signal having a current and a current mode analog-to-digital converter configured to compare the current of the analog signal output by the sample-and-hold circuit to current generated by a plurality of current sources and output a digital representation of the analog signal.
