CIRCUIT ARRANGEMENT FOR GENERATING A REGULATED SMALL SUPPLY VOLTAGE

The invention relates to a circuit arrangement for generating a regulated small supply voltage. The invention relates to a circuit arrangement for generating a regulated small supply voltage (UK) foran operational amplifier (OP) supplied asymmetrically by two operating voltages (UE, UA), wherein the small supply voltage is attached to one pole of an operating voltage (UA) and to an operating voltage input (V-) of the operational amplifier in the order of one tenth of the operating voltage, and a regulated reference voltage source (Q1+Qref; DR) is connected between the pole of the operating voltage (UA) and the operating voltage input (V-) of the operational amplifier (OP). 本发明涉及用于产生经调节的供电低电压的电路装置。一种用于针对由两个运行电压（U、U）不对称地供电的运算放大器（OP）产生经调节的供电低电压（U）的电路装置，其中该供电低电压以运行电压的十分之一的量级附在运行电压（U）的一极与该运算放大器的运行电压输入端（V-）上，其中针对基准电压（U）的经调节的基准电压源（Q1+Q；D）被接到运行电压（U）的这一极与该运算放大器（OP）的运行电压输入端（V-）之间。
