Abstract

PURPOSE:To reduce the influence of an aperture jitter by connecting in parallel the N stages of series circuits each of which consists of a buffer amplifier, an analog gate switch and a holding capacitor and applying the same analog input signal to these series circuits simultaneously to find the additional average of the output voltage of the series circuits. CONSTITUTION:Three stage of series circuits 11, 12, 13 each of which consists of an input buffer amplifier 2, an analog gate switch and a holding capacitor 4 are provided in parallel. The input sides of these series circuis 11, 12, 13 are connected to a common input terminal 1 and respective analog gate switches 3 are controlled by a pulse outputted from a common control pulse input terminal 7. The outputs from the series circuits 11, 12, 13, those are analog voltage held in respective holding capacitors 4, are added in an adder 14 and the average output obtained by dividing the added value by 3 is applied to an output terminal 6. Where, holding voltage of respective holding capacitors 4 are V+Vi<1>, V+Vi<2>i<2> and V+Vi<3>, the holding voltage without aperture jitter is V, respective error voltage due to the aperture jitter are Vi<1>, Vi<2>, Vi<3>i<3>, and the integer is 1.
