Constant voltage circuit has series circuit formed by connecting resistances and series circuit formed by connecting resistance, temp.-dependent semiconducting element and correction element

摘要

The circuit has a bridge circuit with a series circuit formed on one side by connecting resistances (101,102) and a series circuit on the other side formed by connecting a resistance (103), a temp.-dependent semiconducting element (104) and a temp. characteristic controller (200) containing a temp. characteristic correction element (203) with an opposite temp. characteristic to that of the semiconducting element and a differential amplifier (100). The output of the junction of the series circuit on one side of the bridge circuit and the output of the temp. characteristic controller on the other side are connected to the differential amplifier input.
