Implementation of Low Power VLSI Circuit using Pseudo NMOS Logic with Delay Elements S.THANGAMALAR M.E (VLSI DESIGN) P.G.SCHOLAR DEPARTMENT OF E.C.E SRI VENKATESWARA COLLEGE OF ENGINEERING AND TECHNOLOG Email:rachelmalar@gmail.com Abstract-The advent of dynamic CMOS logic‚ more precisely domino logic‚ made them widely used for the implementation of low power VLSI circuits. However‚ the main drawback of this logic is the non implementation of inverted logic. To implement the inverted logic‚ it

Design technique of P-type CMOS circuit for gate-leakage Reduction in deep submicron Aneesha R1‚ Shabnoor Naaz M2 8th Semester‚ E&C Dept‚ BIT Mangalore 1anee.star@ymail.com 2naazshaik.44@gmail.com Abstract— Before the CMOS process is scaled into deep sub-micron process‚ dynamic energy loss has always dominated power dissipation‚ while leakage power is little. The aggressive scaling of device dimensions and threshold voltage has significantly increased leakage current exponentially‚ thus the

Final Project‚ 4-bit Ripple Carry Adder 1. Introduction In this project‚ a 4 -bit ripple carry adder is designed by using dynamic Manchester carry chain. This adder should be designed in Cadence Virtuoso for both schematics and layout. This adder has 9 inputs‚ A0~A3‚ B0~B3 and CLK. When the design is finished‚ it should be checked in HSPICE for the functionality correctness. The worst case delay in this adder should be found by HSPICE as well. 2. Design The figure shown below is the schema

Buck-Converter Design Demystified Stepdown (buck) switching converters are integral to modern electronics. They can convert a voltage source (typically 8 V to 25 V) into a lower regulated voltage (typically 0.5 V to 5 V). Stepdown converters transfer small packets of energy using a switch‚ a diode‚ an inductor and several capacitors. Though substantially larger and noisier than their linear-regulator counterparts‚ buck converters offer higher efficiency in most cases. Despite their widespread use

that allows power to run through. Power then runs to various capacitors to store up power before running to the inductor that converts the power to usable power for the MOSFETs. As the power runs through the circuit‚ it eventually comes to resistors which slow up the current flow. Sound comes in through the inputs and to the MOSFET amplifiers. Then sound goes to the sound dampeners to clean the sound waves up before going to the sound outputs. To better understand the amp and its components we will
