Abstract

PURPOSE:To obtain a large driving voltage when an operational amplifier with a small output voltage is used by supplying a signal passing through the operational amplifier to output the signals of mutually opposite phases between the grid of a CRT and a cathode. CONSTITUTION:An operational amplifier 3 inversion-amplifies an input signal up to the full of positive/negative supply voltages, supplies an output signal to the cathode of a CRT 9, an operational amplifier 2, in the same way, non- inversion-amplifies the input signal from an offset reference level, and supplies the output signal through a capacitor 8 to the grid of the CRT 9. Since the separately amplified signals are supplied to the grid and the cathode, and the signals are mutually at opposite phases, when the gains of the operational amplifiers 2 and 3 are the same, the signal voltages between the grid and the cathode are added with the respective operational amplifier outputs, and the value of them becomes the double of the one operational amplifier output voltage. Consequently, when the operational amplifier with the small output voltage is used, the signal voltage between the grid and the cathode becomes the large value.
