Abstract :
A novel, electronically tunable floating resistor, which can be realized by CMOS technology is presented in this work. The resistance value is independent of the MOS threshold voltage VT, the mobility μ0 and the parameter C0x. The above characteristics allow the implementation of an accurate resistance value, independent of temperature. Yet, a theoretical analysis concerning second order effects is presented which leads to useful conclusions concerning circuit design and operation. The theoretical predictions are verified by PSPICE simulation results
