We propose a CMOS circuit that can be used as an equivalent of resistors. This circuit uses a differential pair consisting of diode-connected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region. Its resistance can be controlled in a range of 1-1000 ㏁ by adjusting the driving current for the circuit. The results of the fabrication and measurement of the circuit are described.
