An original technique for linearizing the I(V) characteristic of the active resistor will be proposed, based on the utilization of a new linear differential amplifier and on a current-pass circuit. The errors introduced by the second-order effects will be strongly reduced, while the circuit frequency response of the circuit is very good as a result of operating all MOS transistors in the saturation region. In order to design a circuit having a negative equivalent resistance, an original method specific to the proposed implementation of the active resistor circuit will be presented.

The validity of the developed models is confirmed by the experimental results of I-V characteristics of pMOSFET before and after stress. Then, the circuit performance prediction is carried out for a 199-stage ring oscillator on its waveform and oscillation frequency. Excellent agreements between experimental results and predicted results are obtained.

Although the technology is constantly being challenged by new promising alternatives, there is still quite some momentum remaining for flash scaling provided the technology becomes more application-specific and more hierarchically integrated with other memories on the system level.
