A threshold compensating circuit generates a bias potential VBIAS, that is, a threshold voltage of a MOS transistor offset by a given value. A gate-source voltage having compensation for variation in threshold voltage is thus applied to a transistor. By using a differential amplifier having this transistor as a current source, a voltage down-converter less susceptible to variation in threshold voltage caused by process variation and temperature can be implemented. |
