Title: Operational amplifier
Inventor: MIYAKE HIDEKI
IPC: H03F1/02
Filed: 1992-10-26
Abstract: PURPOSE:To provide the operational amplifier widened in output dynamic range and reduced in current consumption. CONSTITUTION:In the operational amplifier invented so as to widen the dynamic range, an NPN transistor 35 and a resistor 23 are added in place of a constant current source 63. The collector of the NPN transistor 35 is connected to an output terminal 53, the base is connected to the base of an NPN transistor 33, and the emitter is grounded through the resistor 23. When a voltage is inputted to reduce an output voltage, the NPN transistor 35 is operated, a sucking current from the output is increased, and the dynamic range is widened. When a voltage is inputted so as to widen the output voltage, the NPN transistor 35 is not operated, and current consumption is not almost increased. Thus, the current consumption is not almost increased excepting for the case of reducing the output voltage.
