  • INPUT CURRENT CANCELLATION SCHEME FOR FAST CHANNEL SWITCHING SYSTEMS
    Publication number: 20140079079
    Abstract: A multichannel system, including a multiplexer having inputs for a plurality of input channels, and a pre-charge buffer having a plurality of inputs coupled to an input of the multiplexer, and an output coupled to a multiplexer output. The multichannel system may stand alone, or may be coupled to a receiving circuit having an input coupled to an output of the multiplexer. In some instances, the receiving circuit is an analog to digital converter.

  • Four-quadrant bootstrapped switch circuit
    Patent number: 8604862
    Abstract: A bootstrapped switch circuit includes a first switch transistor to receive an input signal and a second switch transistor to provide an output signal. The sources of the switch transistors may be coupled. A voltage source may be coupled to the sources of the switch transistors and at least one of the gates of the switch transistors. The voltage source may generate a control voltage to activate at least one of the switch transistors based on a bias current. A voltage source driver may be coupled to the voltage source to generate the bias current based on a bias voltage. The bias voltage may include a first voltage approximately corresponding to an overdrive voltage of at least one of the switch transistors and a second voltage approximately corresponding to a threshold voltage of the switch transistors.
