This paper describes the design of a fully differential CMOS amplifier for clipping control circuit. The amplifier with specification of low settling time less than 5ns, high dynamic range above 90dB and low power supply of 3 volt is designed and realized in a 0.35 μm CMOS process with 3 volt power supply. Simulation confirm the presented design.

Keithley’s Series 2300 Battery/Charger Simulators (fast transient response power supplies) are specifically designed for powering RFIC power amplifiers, mobile phone handsets, and other portable, battery-operated products in R&D and manufacturing environments. These battery-simulating power supplies are designed to recover very quickly from short-duration pulse load current changes as large as ...

We present an approach for applying two supply voltages to optimize power in CMOS digital circuits under the timing constraints. Given a technology-mapped network, we first analyze the timing slack distribution and power/delay model within the circuit. The power reduction is then translated into the Maximal-WeightedIndependent-Set (MWIS) problem. We develop an effective power optimization algor...

In recent years, power converters are used to get high power factor for low power applications. In this work, the design and development of a DC-DC Converter using two stage buck–boost converter with isolation operation as high-power-factor offline power supply for power-LED lamps is discussed. This converter is suitable for low power application such as a matrix LED lighting system. The advant...

In order to cope with the increasing leakage power and the increasing device variability in VLSI’s, the required control size of both the space-domain and the time-domain is decreasing. This paper shows the several recent fine-grain voltage engineerings for the low power VLSI circuit design. The space-domain fine-grain voltage engineering includes the fine-grain power supply voltage with 3D-str...

A low-voltage power supply circuit is developed for micropower CMOS LSI applications, especially for microwatt smart-sensor LSIs. The circuit consists of a switched-capacitor voltage converter and a series regulator. The switched converter lowers battery voltage 1.5–3V to a low voltage of 0.5–0.7V to drive the series regulator, and the series regulator provides LSI logic gates with a power volt...

A compact, very low voltage, temperature-independent reference circuit, which is based on the thermal properties of bipolar junction transistors in the saturation region is presented. The new circuit operates from a minimum power supply of less than 1V and provides a reference voltage with a nominal thermal drift of 30 ppm/8C in the temperature range between 240 and 1108C. The proposed circuit ...

Electronic circuits require a wide variety of voltage levels to operate correctly. A DC/DC converter (DC/DC) is an electronic circuit used either to transform one voltage level to a different level; or to provide an isolation barrier for a voltage bus. DC/DCs are typically used in power distribution systems to provide a local voltage conversion, point of load voltage regulation or power bus iso...

Better prediction of electromagnetic compatibility (EMC) for components is becoming a topical demand, due to technology improvements. It is requested by integrated circuit (IC) manufacturers as well as by equipment integrators. The French UTE standardisation group has proposed an EMC modelling methodology for ICs, called ICEM (Integrated Circuit Electromagnetic Model). This proposal improves an...
