Abstract

See full text

The invention provides an analog circuit that decreases an effect of variation of a transistor. By flowing a bias current in a compensation operation, a voltage between the gate and source of the transistor to be compensated is held in a capacitor. In a normal operation, the voltage stored in the compensation operation is added to a signal voltage. As the capacitor holds the voltage according to the characteristics of the transistor to be compensated, the effect of variation can be decreased by adding the voltage stored in the capacitor to the signal voltage. Further, an analog circuit which decreases the effect of variation can be provided by applying the aforementioned basis to a differential circuit, an operational amplifier and the like.
