Abstract

PURPOSE:To stabilize the gain of an A/D converting circuit by changing the correction voltage which is outputted by a digital stabilizer, to a correction input of the constant-current source. CONSTITUTION:The voltage VS supplied from the constant-current source 15, and the correction voltage VC supplied from a digital stabilizer 14 are provided to the A/D converter 13 through the differential amplifier 16 and the amplifier 12. The digital stabilizer 14 compares the value which has been digitally converted as to the crest value of a reference pulse, with the reference value Vr. The correction voltage VC is varied in accordance with said comparison result. Also, when this correction voltage VC is varied, a current I is varied and the conversion gain of the circuit 13 is controlled.
