Patent

CA 2673699

A bias controller which can adjust a bias voltage of a FET without accidentally setting the bias voltage to a voltage which damages the FET, is provided. The bias controller includes temperature detector 351 configured to detect ambient temperature of FET (Field Effect Transistor) 12, 1st voltage generator 2 configured to generate a voltage signal for temperature compensating of a positive voltage based on an output of temperature detector 351, 2nd voltage generator 3 configured to generate a bias voltage signal of a positive voltage, and operational amplifier 33 and 34. Each operational amplifier 33 and 34 is individually configured to add the voltage signal for temperature compensation and the bias voltage signal, and to perform inverting amplification to generate the bias voltage of negative voltage to be applied to FET 12 and 22.
