Abstract

PURPOSE: To enable temperature correction of a broad range, by adding a signal relating to a voltage between base and emitter of the 1st transistor, with a signal relating to the collector current of the 2nd transistor, and taking the result of addition as the power supply of a bridge circuit including a distortion resistor.
CONSTITUTION: The output voltage -E of a bridge power supply DS consisting of a DC power supply ES, voltage dividing resistors r6, r7 and r8, r9, transistors Q1, Q2 and an operational amplifier OP1 providing a feedback resistor r2, is fed to a bridge circuit B. The operational amplifier OP1 adds a current i1 flowing to a resistor r1 and i3 flowing to a resistor 10, and a voltage -E of -E=r2(i1+i2)=-(v1+ v2) is fed to the bridge circuit B through a resistor r2. The current i2 exponentially increases with a higher temperature range than a room temperature to compensate the temperature characteristics of the bridge circuit with a wide temperature range.
