“…It happens because the source and drain terminals of the MOSFET become to be closer. [14][15][16][17][18][19][20][21] As a result of that, the gate terminal of the MOSFET starts to lose the control of the channel. Those undesirable effects which causes negative behaviour of transistor are called "short-channel effects" (SCE).…”

Barrel shifter architecture is well known for bit manipulation in a single clock cycle. Due to its various operations and advantages, it is most likely used in the Arithmetic logic unit of every processor. Gray code is also known as reflective code which is widely used in digital communication for the purpose of error correction and error detection. In this project, an 8 x 4 barrel shifter is designed which is further connected to 4-bit binary to gray code converter. The barrel shifter is cascaded with binary to gray code converter so that this combination can be useful for the application of encryption of binary data in digital communications. It is designed in cadence virtuoso tool using FinFET technology at 18 nm node. The simulation results proves that the power consumed by the proposed design with FinFET technology is 11.92% less when compared with the conventional design with MOS transistors. Hence, this design can be used in application of low power digital communications. The functionality testing and verification is done using cadence virtuoso tool.

A robust square wave generator employing a sole capacitor and two resistors has been presented in this study. Low power as well as popular translinear circuit scheme of Second generation current controlled current conveyor-CCCII has been taken as an active element to implement the proposed square wave generator. CCCII inhibits promising features like availability of three mutually independently and electronically adjustable parameters corresponding transconductance (g m), intrinsic resistance (r) of the current input terminal and current gain between two terminals) that are very prevalent for control applications accepted currently. The operating frequency of the proposed model has been analyzed with respect to the passive components present there, with no exposure of output signals to the thermal voltage (V T). Electrical/Device properties (like Noise, Threshold, area etc.) of the proposed circuit have also been discussed in this work. The simulation work was carried out on Synopsis Hspice tool (v-2008.03) from Avant. Satisfying results with anticipation of theoretical and simulated results, including precision (consistency assessment) with Pareto analysis (Ist order Best Test flavored by Decision making analysis) were observed during the study. The 45 nm BSIM CMOS modelling parameters were adopted to prove the theory. The elementary purpose of using such parameters is to maximize the circuit drive and lowering the leakage current. Another purpose of using these modelling parameters is to enhance the realization of the proposed circuit in the form of chip die and further get it fabricated in custom Integrated circuit(IC) form, from a Standard local foundry. Maximum power consumption of the circuit is 600 µW, with ± 1 V rail to rail operating voltages.

: This paper brings in a new design, namely, voltage mode differentiator with an active element, Carbon Nanotube Field Effect Transistors Voltage Difference Transconductance Amplifier (CNVDTA). The circuit thus proposed needs one Carbon Nanotube Field Effect Transistors Voltage Difference Transconductance Amplifier (CNVDTA) element and a single capacitor. While fabricating IC’s in VLSI design, the proposed circuit proves more adaptable and applicable with the anticipated results. Methods: The proposed CNVDTA based voltage mode differentiator in CNFET technology was simulated at 32 nm at a voltage supply of ±0.9 V using the Cadence Virtuoso CAD tool. Results: It is also reported that the proposed circuit would function with ±0.9 V supply voltage and would also take care of the bias current of the order of 150 µA. Further, on the part of the transconductance (gm), it is electronically tunable with the help of bias current. Conclusion: The CNVDTA based differentiator has been found to be very useful in the triggering circuit of CRO’s, wave shaping circuits, power control circuits etc. It is also found useful in detecting the high-frequency components in the input signals.
