Fully Integrated High-Voltage Generators with Optimized Power Efficiency

An Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)

this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...

High Voltage Power Condition Systems Powered by Flux Compression Generators*

Compact, high-gain magnetic flux compressors (FCGs) are convenient sources of substantial energy for plasma-physics and electron-beam-physics experiments, but the need for highvoltage, fast-rising pulses is difficult to meet directly with conventional generators. While a variety of novel concepts employing simultaneous, axially-detonated explosive systems are under development, power-conditioni...

Power Efficiency Optimization of Fully Integrated Dickson Charge Pumps

This paper describes how the power efficiency of fully integrated Dickson charge pumps in advanced smart power technologies can be improved considerably by implementing charge recycling techniques and the replacement of normal PN junction diodes by pulse-driven active diodes. These 2 methods are first analyzed and compared on a purely theoretical basis and are verified with experimental data af...

Fully Integrated CMOS Power Amplifier

Low voltage Low Power Fully Differential Buffer

In this letter a useful CMOS fully-differential buffer topology is presented. The proposed solution, performing the common mode feedback (CMFB) operation, shows a rail-to-rail characteristic, so it is particularly suitable for low-voltage (± 0.75V) low-power (<400 μW) applications. The simulated results have shown excellent general performance, evaluated in terms of suitable figures of merit (F...
