  • High speed, high voltage multiplexer
    Patent number: 8493255
    Abstract: A method for digitizing at least a portion of a selected analog input signal of a plurality of analog input signals by using a multiplexer having a plurality of channels is provided. Each channel for the multiplexer is associated with at least one of the analog input signals and is associated with a pair of select signals, and wherein each channel includes a cell having an input terminal, an output terminal, and a boosted NMOS switch. According to the method, a first select signal from each pair of select signals is asserted to decouple the input and output terminals for each cell. A boost capacitor is also charged during the non-sampling or conversion phase while the first select signal from each pair of select signals is asserted.
