Abstract
Values of control signals, each inputted to an input terminal for operation controlof each of transistor elementsconstituting a variable resistance portion, are controlled based upon an input signaland offset signalsgenerated by an offset provision portion. Thus, a ratio of the maximum resistance value to the minimum resistance value can be made large, while using a limited power supply voltage range as a control range.
