We present the design and the test performed on ADeLinel, a Full-Custom Analog Memory for sparse data sampling. It has been designed as an array of switched capacitors. It is only one channel of 8 cells. The control part of the ADeLine chip is custom designed for the size reduction, high speed performance and low power dissipation. The memory has been integrated in double poly, double metal AMS...

The increasing interest in renewable energy sources has brought attention to large voltage-gain dc–dc converters; among the different available solutions perform a conversion, this article presents an overview of non-isolated converter topologies that utilize switched-capacitor circuits, i.e., diode-capacitors voltage multipliers. review includes combinations traditional power stage with diode-...

High voltage gain DC-DC boost converters are widely used in grid-connected applications through integration with the Renewable Energy Sources (RESs). Photovoltaic (PV) arrays or Fuel Cells (FCs) generate a limited value of DC voltages and then for high power applications, at first stage, these should be increased. This study presents gain, single-switched, efficient converter using switched-cap...

This paper presents a di erential input ash ADC with digital common mode rejection (DCMR) and dithered, noise shaped requantization used in a high-performance, single-poly CMOS ADC modulator IC. By avoiding the use of metal-metal capacitors, the DCMR ash ADC required 14% less area than a switched-capacitor implementation and avoided circuit implementation problems. Measurements and analysis sho...

An incremental ADC for Wheatstone CMOS stress sensor systems is described. A switched-capacitors integrator without switches toward virtual ground avoids spur signals, clock feed-through, residual offset and glitches. The circuit, fabricated in a 0.35-μm CMOS technology, consumes 42 μW at 500-kHz clock and 2.8-V supply. Low speed chopping cancels offset and limits the 1/f noise contribution. Th...

Voltage instability occurs in power systems when the system is unable to maintain an acceptable voltage profile under an increasing load demand and/or configuration changes. The operating conditions of the present day distribution systems are closer to the voltage stability boundaries due to the ever increasing load demand. This paper presents a new algorithm for optimal locations and sizing of...

A double-sampling highpass delta-sigma modulator (HPDSM) with inherent frequency translation is presented. The switched-capacitor highpass filter with double-sampling not only minimizes the number of capacitors required in the feedback network but also enables chopper stabilization which makes the modulator immune to 1/f noise and DC offset. A first-order prototype HPDSM with 3bit quantization ...

In this paper, topology of a Grid connected solar microinverter is proposed. The DC power obtained from the solar panel is converted into a rectified AC signal. This conversion is realized by an Active Clamped Flyback Converter. A full-bridge inverter which switched at a high frequency converts this rectified AC into sinusoidal AC of power frequency and this also controls the power flow directi...

Switching circuits with thyristor controlled reactors are used in high power systems for static VAR control and flexible AC transmission. These circuits can exhibit highly nonlinear behavior because the thyristor switch off time depends on the circuit state. This paper shows how to understand and predict damping and resonance in a basic thyristor controlled reactor circuit used for static VAR c...

This paper demonstrates the feasibility of implementing wide tuning band low phase noise oscillators in low cost Sibased integration technologies. For that, it is necessary to use radio-frequency switched capacitors arrays (RFSCA) and differentially tuned anti-parallel varactors. To corroborate this idea, a voltage controlled oscillator (VCO), designed in a low cost 0.35 μm CMOS technology, is ...
