Abstract: In this paper a voltage mode differentiator (First order high pass filter) and voltage mode integrator (First order low pass filter) have been proposed by using currentcontrolled current differencing buffered amplifier (CCCDBA). In the present work, an effort has been made to control the first order filters parameters electronically, adjusting bias current of CCCDBA. The designed circuits are very suitable for integrated circuit and very easy in implementation. The circuit performance is simulated through PSPICE and its simulated results obtained so is comparable to the theoretical one.

Abstract: Our life is filled by various modern electronic products. Semiconductor memories are essential parts of these products and have been growing in performance and density in accordance with Moore's law like all silicon technology. The process technology has been scaling down from last two decades and to get the functional and high yielding design beyond 100-nm feature sizes the existing design approach needs to be modified to deal with the increased process variation interconnects processing difficulties, and other newly physical effects. Considerable increase in gate direct tunneling current in the nano-CMOS regime is because of scaling of gate oxide. Subthreshold leakage and gate direct tunneling current are no longer second-order effects. The effect of gate-induced drain leakage (GIDL) is easily visible designs, such as DRAM and low power SRAM. All these effects cannot be ignored as it will lead to nonfunctional SRAM, DRAM, or any other circuit. Reducing the supply voltage which is now
