Abstract
1528000 Automatic control of voltage NIPPON KOGAKU KK 22 Dec 1975 [26 Dec 1974] 52381/75 Heading G3R A constant voltage generating circuit includes an operational amplifier with feedback from a circuit, connected to the amplifier output, which provides the constant voltage. The feedback to one amplifier input is via an element (eg diode or transistor) the voltage across which is logarithmically proportional to the current through it, the other amplifier input being connected to a voltage supply through a similar element. As shown, the inputs of operational amplifier A are connected, through resistors R 2 R 3 to one input 1a of an unstabilized voltage source E, the non-inverting input via diode D2 to a voltage divider R 4 , R 5 across the amplifier output, and the inverting amplifier input to the other source terminal 1b via diode D 1 . The output voltage Vo, as derived in the description, depends only on R2, R 3 , R 4 , R 5 and absolute temperature. The output may be used to supply an automatic exposure control in a camera, or as a temperature compensation circuit for semi-conductors. In other embodiments, Figs. 2 and 3 (not shown), the output voltage, or a constant current, is obtained from an emitter follower circuit, connected to the amplifier output and including a transistor (eg an FET). The feedback circuit, from the transistor collector, is then via a diode or a further transistor.
