Title: Offset compensation circuit
Inventor: OYA YASUNORI
IPC: H04L27/38
Filed: 1989-03-29
Abstract: PURPOSE:To always keep an offset to an optimum value stably by compensating a change in the offset value due to a cause other than temperature fluctuation and applying proper compensation even when a temperature fluctuation different from prediction takes place. CONSTITUTION:A change in the offset value of a demodulation base band signal is detected as a change in an analog signal voltage of D/A converters 31a, 31b in an offset compensation circuit 30. When the analog signal voltage changes, operational amplifiers 33a, 33b respectively detect the direction of deviation from a normal value and its deviation and a correction voltage to make the deviation direction or shift zero is added to an offset voltage Vref respectively. The corrected offset voltage Vref' is fed respectively to operational amplifiers 14a, 14b, from which the voltage is added to a demodulated base band signal. Thus, the change in the offset voltage due to the superimposition of a DC component and temperature fluctuation is all surely compensated.
