  • Charge source multiplexing
    Patent number: 4361839
    Abstract: A charge-mode signal conditioning interface includes a charge-mode signal multiplexer for providing a low impedance series path for the output charge signals from each charge source to the input of the common charge amplifier, one at a time in each sample time interval of a repetitive sequence of sample time intervals and non-sample time intervals for each source, and for providing a low impedance shunt path for each charge source in each non-sample interval.
