This paper describes a CMOS voltage reference circuit which occupies small die area and has less than 1.25 V of output voltage. The reference voltage is determined by a resistor ratio, and it is possible to set the reference voltage from zero to near the supply voltage with the same temperature independence as those of Widlar’s and Brokaw’s bandgap voltage references. The temperature-independen...

Level shifter is an interfacing circuit which can interface low core voltage to high input-output voltage. It allows communication between different modules without adding up any extra supply pin. The main objective of the work is to minimize power dissipation in shifter circuit, which is due to different supply voltages in the circuit. The proposed method uses MTCMOS technique, which is one of...

The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages and fundamental edge currents. Every steady-state DC circuit can be decomposed into a voltage controlled subcircuit and a current controlled s...

This paper presents positive and negative full-wave rectifier. The proposed structure is based on OTA using commercially available ICs (LT1228). The features of the proposed circuit are that: it can rectify and amplify voltage signal with controllable output magnitude via input bias current: the output voltage is free from temperature variation. The circuit description merely consists of 1 sing...

In this paper, a novel single-port five-transistor (5T) Static Random Access Memory (SRAM) cell and associated read/write assist is proposed. Amongst them, a word line suppression circuit is to provide a voltage of the respective connected word line to be lower than the power supply voltage VDD, as such the read/writeability of the cell can be improved and the half-selected cells disturbance ca...

A new low-power design method based on multiple low swing internal voltage values is proposed in this paper. It can be applied in logic circuits, which are designed with different logic family techniques such as Complementary Pass Transistor Logic (CPL), Domino Logic and Cascade Voltage Switch Logic (CVSL). The goal of this method is the reduction of the circuit power dissipation, with only a n...

Due to the decade of fossil fuels at present renewable energy plays an important role in generating power to meet the load requirements. Power produced from the renewable energy is very low. So chopper circuit is required to boost the voltage level of renewable energy sources. Chopper is a circuit in which fixed DC voltage is converted into variable voltage. There are many types of chopper circ...
