An Isolated Off-Line High Power Factor Electrolytic Capacitor-Less LED Driver with Pulsating Output Current

One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...

A Low Voltage Switched-Capacitor Current Reference Circuit with low dependence on Process, Voltage and Temperature

A low voltage switched-capacitor circuit that generates an almost constant reference current across process, voltage and temperature (PVT) is proposed. The reference voltage is generated by a low voltage band-gap circuit. The output reference current is obtained by applying the generated reference voltage to a low voltage V – I converter. The resistor in the proposed V – I converter is further ...

Low-voltage Switched-capacitor Resonators

The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the feature sizes in CMOS technology, and hence higher levels of integration. enable the combined integration of a bandpass or baseband analog-to-digital converter with the traditional front-end receiver building blocks. While ths t...

Low-voltage switched-capacitor circuits

One of the key limitations of state-of-the-art fine linewidth CMOS technologies is the restricted power-supply voltage, limited by the low junction-breakdown voltage of the process and by the thin gate oxide, prone to voltage stress and breakdown. Also, in some applications, the available external power source may limit the supply voltage; for example, this source may be a 1.2 V battery, with a...

Design of an LLC Resonant Converter for Driving Multiple LED Lights Using Current Balancing of Capacitor and Transformer

In this study, to achieve the constant current drive and brightness control without a separate pulse width modulation (PWM) converter, a single converter is designed and verified by experiment under the condition of a multiple LED light load with different output voltage (Vf) characteristics. In the case of the input of 140 Watt class level, the proposed converter can drive two voltage type 95 ...
