Research Abstract

Circuit techniques to enhance linearity of the voltage-to-current(V/I) converted input signal by using a linear resistor with the V/I-converted current feedback scheme and to increase the output impedance of a current source by using the V/I-converted current feedback scheme for compensating the low intrinsic gain of a transistor are developed.
In future analog circuits and ICs in sub-100 nm CMOS processes, it is considered that the low supply-voltage operation below 1 V and low intrinsic gain(gm/gds) of a MOS transistor become dominant obstacles for LSI circuits. We, in this research, have been able to develop circuit techniques to sweep away those possible obstacles in future analog circuits.
