Title: Absolute value circuit
Inventor: OWATARI KEIJI
IPC: H03D1/10
Filed: 1994-01-20
Abstract: PURPOSE:To attain temperature compensation and to suppress the error of arithmetic output by providing a temperature coefficient on circuit output so as to cancel a temperature drift at a DC bias point in an absolute value circuit. CONSTITUTION:When the temperature coefficient of a current source I1 is different from that of a current source I2, relation I2=2XI1 is satisfied in room temperature. When the above relation is not satisfied by the change of ambient temperature, a collector current on a transistor TrQ2 is not equal to that on a transistor TrQ3 by temperature change. Therefore, the base/emitter voltage of the transistor TrQ2 is not equal to that of the transistor TrQ3. When the temperature drift occurs at the DC bias point by an input signal or the temperature characteristic of an out-fitted component, the temperature coefficient so as to cancel the temperature drift is attached on the current sources I1, I2. In this way, it is possible to keep the DC bias point constant in spite of the temperature change and to suppress the error of the arithmetic output.
