Abstract
PURPOSE: To obtain an output signal whose linearly is satisfactory, by constituting so that an input signal and a reverse signal are applied to two FETs having the same characteristics, respectively, and supplying a difference of each drain of each FET to a load.
CONSTITUTION: When an input signal Vi is supplied to an input terminal T1, a current i1 flows to the drain of an FET6. Since an FET3 and an FET4 have the same characteristics, a reverse signal of -Vi is generated between the source and the gate of the FET4, and is supplied to an FET8. Since the FET6 and the FET8 have the same characteristics, when a difference current between a current i2 flowing out from the source of the FET8, and the current i1 flowing to the FET6 is denoted as i3, a current flowing to a load 11 becomes a value which has subtracted the difference current i3 from a current I flowing out from a constant-current source 10. When voltage V0 across the load resistance 11 is outputted as an output signal, the output signal whose linearity is satisfactory to the input signal is obtained.
