Abstract

PURPOSE:To reduce the effect of the capacitance change of the capacitor, by performing the charge and discharge to the capacitor, at a fraction of time for the converted signal period. CONSTITUTION:When the converted signal is fed to the input terminal IN1, the counter CT starts counting the clock pulse, the capacitor C is discharged by closing the charging switch S1 with the output of the output terminal A, and the flip flop FF2 is operative to positive simultaneously, and the sampling switch S2 is opened. After a given time, the conrtant current source is driven with the output of the output terminal B, the capacitor C is charged up and the charge is finished with the next conversion signal incoming.
