In this paper we present a photovoltaic energy harvester, realized in 0.35-μm CMOS technology. The proposed system collects light energy from the environment, by means of 2-mm2 on-chip integrated micro-solar cells, and accumulates it in an external capacitor. While the capacitor is charging, the load is disconnected. When the energy in the external capacitor is enough to operate the load for a ...

Application specific full custom design integrated circuit is a methodology for making a logic cell, circuit or layout specification. Full custom design circuit is the part of Application specific integrated circuit. A gate array or uncommitted logic array as an approach to the design and manufacture of application specific integrated circuit. It requires custom chip fabrication using a complet...

In this paper we give an overview of tasks, models and mixed-signal simulation tools to support design of digitally controlled switching power supplies where the digital controller is implemented in a dedicated FPGA or ASIC. Mixed-signal simulation models of a digitally controlled switching converter based on Matlab/Simulink and HDL/Spice simulation tools are presented. The models are used in t...

Circuit-level implementation of a novel neuron has been discussed in this article. A low-power Activation Function (AF) circuit is introduced in this paper, which is then combined with a highly linear synapse circuit to form the neuron architecture. Designed in Carbon Nanotube Field-Effect Transistor (CNTFET) technology, the proposed structure consumes low power, which makes it suitable for the...

To meet the ever-increasing demand of high performance systems, more and more functions are integrated into single chip by scaling down the size of device. Leakage current is becoming an increasingly important fraction of total power dissipation of integrated circuits. As technology scales leakage current grows exponentially and become and increasingly large component of total power dissipation...

This paper presents a -band push–pull power amplifier integrated with a modified uniplanar quasi-Yagi antenna. In this circuit, corrugation is added to the truncated ground plane of the antenna so that it can be used for both out-of-phase power combining and second harmonic tuning. By using the active integrated antenna concept, this novel circuit eliminates the usage of an ordinary 180 hybrid ...

This study presents a performance analysis of low power CMOS Integrated “Current Conveyor Ion Sensitive Field Effect transistor” (CC-ISFET). The study’s main focus is on simulation of power and performance analysis of ISFET device, which is used for water quality monitoring. This approach can improve calibration of device to a fairly wide range without the use of a high speed digital processor....

Introduction: The development of designs for test techniques continue to receive a great deal of consideration [l]. Techniques based on scan is one of the most effective methodologies and has been adopted widely in the area of digital integrated circuit design. When testing systems with scan design, the entire scan registers (SRs) andor combinational modules are always active during the whole s...

On-chip power dissipation has become a fundamental design issue in high performance integrated circuits. A technique to significantly reduce the power dissipated in the non-critical data paths of an industrial circuit is demonstrated. The application of this technique with non-zero clock skew scheduling to the slower data paths is also described. Simulation results demonstrating the application...
