Active clamped ZVS forward converter with soft-switched synchronous rectifier for high efficiency, low output voltage applications
Acik, A; Cadirci, I (Institution of Engineering and Technology (IET), 2003-03-01)
The analysis, design, and implementation of an active clamped ZVS forward converter equipped with a soft-switched synchronous rectifier (ACFC-SR), proposed for high-efficiency low output voltage DC-DC converter applications, is presented. The converter efficiency is maximised due to soft switching of the main, active clamp, synchronous rectifier, and freewheeling MOSFET switches. The operating principles of the ACFC-SR are analysed in detail, and the converter performance is compared with that of alternativ...
Fully Integrated Ultra-Low Voltage DC-DC Converter with Voltage Quadrupling LC Tank Oscillator for Energy Harvesting Applications
Jayaweera, H. M. P. C.; Tabrizi, Hamed Osouli; Muhtaroglu, Ali (2017-12-02)
This paper presents a novel fully integrated ultra-low voltage DC-DC converter and its multi-stage architecture. DC-DC converter frequency has been analytically derived using model analysis and validated in Cadence environment. The proposed voltage quadrupling LC tank oscillator eliminates the buffer circuits utilized in the traditional DC-DC converter, hence improves the performance metrics such as efficiency and output power capacity. The circuit was designed in 180nm standard CMOS process and was simulat...

Fully Integrated Ultra-Low Voltage Step-up Converter with Voltage Doubling LC-Tank for Energy Harvesting Applications
Jayaweera, H. M. P. C.; Pathirana, W. P. M. R.; Muhtaroglu, Ali (2015-12-04)
This paper reports the design, fabrication, and validation of a novel integrated interface circuit for ultra-low voltage step up converter in 0.18 mu m CMOS technology. The circuit does not use off-chip components. Fully integrated centre-tap differential inductors are introduced in the proposed LC oscillator design to achieve 38% area reduction compared to the use of four separate inductors. The efficiency of the system is hence enhanced through the elimination of clock buffer circuits traditionally utiliz...
