The issue of developing a behavioral model of pulse voltage converter IC is considered on the example of a microcircuit of domestic production 1290EF1. In order to verify the adequacy of the model, taking into account its frequency characteristics, recommendations and basic requirements are given when performing a full-scale and numerical experiment to determine the frequency characteristics of such type of nonlinear dynamic objects.

A Novel Approach to Investigate Analog and Digital Circuit Applications of Silicon Junctionless-Double-Gate (JL-DG) MOSFETs

The double gate junctionless transistor (DG-JLT) has become the most promising device in sub nano-meter regime. DGJLT based circuits have improved performance and simpler fabrication than their inversion mode counterparts. This paper demonstrates the design of different analog and digital circuits using DGJLT. Amplifiers and inverters are the basic building block of electronic ICs. A MOS amplifier converts the variation of the gate to source voltage to a small current under transconductance and hence, the output voltage. A single-stage amplifier and differential amplifier have been designed with junctionless-double-gate (JL-DG) MOSFET. Trans-conductance, output voltage, and gain have been investigated using ATLAS 2D device simulator. The inverter is the primary logic gate that can be used to verify the device's response in digital applications. Further, CMOS inverter have been designed using JL-DG MOSFET, and its performance parameters such as switching voltage, noise margin, and logic delay have been analyzed. A switching voltage of 0.43 V, noise margin of 0.265 V, and a delay of 19.18 psec have been obtained for the basic cell. CMOS inverter using JL-DG MOSFET at 20 nm technology node have prompted better performance results. Thus, The JL-DG MOSFET has a bright future in low-power analog and digital applications.
