Title: Analog-to-digital converter
Inventor: MINAMI MUNEHIRO
IPC: H03M1/12
Filed: 1981-01-09
Abstract: PURPOSE:To perform high-precision digital conversion, by obtaining a constant value of unit charging free from variation in voltage. CONSTITUTION:A reference voltage VR is supplied to an input terminal 33 and when a signal P5 which has the crest value of the same potential rises, MOS transistor TRs 34 and 35 turn on and off, respectively. Therefore, a voltage obtained by subtracting the threshold voltage VTH of the TR34 from the voltage VR is supplied to a capacitor C3, which is charged. As a result, a gate signal P2 also reaches a level VR-VTH. When the input signal P4 of this voltage VR rises, the signal P2 is to increase up to about 2VR-VTH, but an MOSTR32 turns on, so the voltage of the signal P2 drops, so that the TR32 turns off when the drops down to the VR+VTH. Therefore, the signal P2 is stablilized at the VR+ VTH. Then, a voltage at a connection point (b) is stabilized at a VR. Thus, the output of an A/D converting circuit 31, i.e., the count value of a counter circuit 18 is free from the influence variation in voltage VTH.
