Fault logic circuit design of switching power supply based on soft reference circuit module

Module 3: Logic Circuit Structure

This module presents the basic structure of combinational logic circuits, and introduces the use of computer aided design (CAD) tools in modern circuit design. Combinational logic circuits use networks of logic gates to produce outputs that change in strict relation to input changes; that is, an output can only change state immediately after an input changes state. In a combinational circuit, s...

Power supply noise coupling in a standard voltage reference circuit

Design of Low Power Fault Coverage Circuit Using LT-LFSR

Abstact A new design approach is proposed for a fault coverage circuit. In this design a linear feedback shift register which is called as LT_LFSR (Low Transition Linear Feedback Shift Register) is used. Using LT_LFSR reduces the power consumption by reducing the number of transitions during test mode. Power reduction is done by implementing two new test pattern generation methods in LFSR. In b...

Low power combinational circuit based on Pseudo NMOS logic

Different logic families have been proposed from several years to improve the performance of the high speed circuits. Mostly used logic family is CMOS which requires equal number of nMOS and pMOS transistor but in some application it may be required to reduce the area. Pseudo nMOS logic is one of the alternative for that .In this paper, NOR-XOR, NAND-XOR and other combinational circuit using ps...

Circuit Sizing and Supply-Voltage Selection for Low-Power Digital Circuit Design

This paper analyzes energy minimization of digital circuits operating at supply voltages above threshold and in the sub-threshold region. Circuit sizing and supply-voltage selection are simultaneously analyzed to determine where the minimum energy solution occurs. In this work we address the effects of architectural modifications on the design choices in different regions of operation. Two new ...
