The minimum supply voltage in low-voltage circuits can be defined as Vsup,min = 2(Vgs+Vsat) [1]. Low-voltage circuits are able to operate on a supply voltage of two stacked gate-source voltages and two saturation voltages. Differential amplifiers are biased with a transistor feeding a differential pair, where the current level is set by the bias transistor. The minimum input voltage in a NMOS i...

the rapid scaling in modern cmos technology has motivated the researchers to design new analog-to-digital converter (adc) architectures that can properly work in lower supply voltage. an exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. this paper is going to review the recent development in t...

In this paper, we show that the temperature-induced performance drop seen in nanoscale CMOS circuitscan be tackled by powering the circuits with adaptively regulated voltage power supplies. Essentially, when temperature rises, the supply voltage will be bumped up to offset otherwise performance degradation. To avoid thermal over-drift as chip temperature exceeds its operation range, a voltage l...

A 2.5V high precision BiCMOS bandgap reference with supply voltage range of 6V to 18V was proposed and realized. It could be applied to lots of Power Management ICs (Intergrated Circuits) due the high voltage. By introducing a preregulated current source, the PSRR (Power Supply Rejection Ratio) of 103dB at low frequency and the line regulation of 26.7μV/V was achieved under 15V supply voltage a...

Objective Preferably (in general) electronic circuitry is energized from a voltage source, i.e., a source for which ideally no current flows under open-circuit conditions. Absent the need to maintain the load current stand-by power dissipation will be minimal. In addition a DC (unipolar constant voltage) power supply virtually always is preferable over an AC supply for electronic equipment. An ...

A resistorless CMOS nonbandgap voltage reference, which is compatible with 180nm CMOS Technology is presented in this paper. In order to reduce the temperature nonlinearity in proposed voltage reference, threshold voltage and a proportional to absolutely temperature (PTAT) voltage form the basic linear temperature components, which are achieved by resistorless threshold voltage extractor and di...

—In this paper, we present a method to design low-power low-voltage current-mirror based integrators for continuous-time modulators. It is shown that, by proper biasing of the mirror transistors, very high modulation index can be achieved at low-voltage supply. Careful analysis of the current-mode integrator shows that there exists an optimum supply voltage for minimum power consumption. Simula...

To develop a well designed practical spring-roll dielectric elastomer actuator system, we have to optimize its design parameters. In our pervious work, we have achieved the design parameters without taking the applied voltage required to activate the actuator into consideration because the applied voltage might change the optimal design parameters. In the paper, optimal design parameters have b...
