Solid-state circuit breakers (SSCB) show great promise to become the key element in protection of low-voltage direct current microgrids. SSCBs operate microsecond range and employ semi-conductor devices that have strict safe operation area limits. Therefore, design SSCB needs consider effects fault detection delays limitations. This paper derives criteria effect different methods with under var...

Low Dropout (LDO) Voltage Regulators are the linear regulators which drives upon a very small differential voltage. The main components of dropout voltage Error amplifier, Pass device, reference source and divider network. low regulator uses variable input to give steady, constantly controlled, low-noise DC output This is that includes drop among as well works even when extremely close amplifie...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

To proof low voltage techniques are valid in current conveyor design, Bulk driven and composite transistor (self cascode) techniques are used to get high performance results from CCII in low voltage supply. Conventional operational amplifier circuit from literature was our choice as core of the design. Our Focus with using low voltage techniques is study the frequency characteristics of a CCII ...

In this paper, a new low-voltage MOS current mode logic (MCML) multiplexer based on the triple-tail cell concept is proposed. An analytical model for static parameters is formulated and is applied to develop a design approach for the proposed low-voltage MCML multiplexer. The delay of the proposed low-voltage MCML multiplexer is expressed in terms of the bias current and the voltage swing so th...

in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...

This paper concerns the design, implementation and subsequent experimental validation of a low-voltage analog CMOS switch based on a gate-bootstrapped method. The main part of the proposed circuit is a new low-voltage and low-stress CMOS clock voltage doubler. Through the use of a dummy switch, the charge injection induced by the bootstrapped switch is greatly reduced resulting in improved samp...

Mixed and analog systems design with high performance suffers from many difficulties due to supply voltage, power consumption and area overhead. A need for low-voltage low-power operational amplifiers exists and used for some applications. This paper deals an effective OTA design for good PSRR, low-voltage, low-power and wide output voltage swing operational amplifier. Trying to combine an alte...
