This study presents a tunable dual-band gallium nitride (GaN) power amplifier (PA) operating in L-band. The first band is aimed near the lower edge of the L-band, 1GHz, and the second band is aimed near the upper edge of the L-band, 2GHz, which is located around the second harmonic of the first band. A pin diode-based tunable load matching circuit is proposed and designed in order to present the optimum fundamental and harmonic load impedances to the transistor in both operating bands for maximum efficiency and output power. A method of controlling the tunable load matching circuit according to the input frequency is proposed by the design of a band-selective power detection circuit incorporated into the source matching circuit of the PA. The implemented PA delivers 41.5dBm output power with 81.3% drain efficiency (DE) at 920MHz and 41dBm output power with 60.2% DE at 1720MHz.

An Adaptable Interface Circuit With Multistage Energy Extraction for Low-Power Piezoelectric Energy Harvesting MEMS Chamanian, Salar; Ulusan, Hasan; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-03-01) This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy. The circuit is optimized to operate...
A Self-Adapting Synchronized-Switch Interface Circuit for Piezoelectric Energy Harvesters Chamanian, Salar; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01) This paper presents a self-adapting synchronized-switch harvesting (SA-SSH) interface circuit to extract energy from vibration-based piezoelectric energy harvesters (PEHs). The implemented circuit utilizes a novel switching technique to recycle optimum amount of harvested charge on piezoelectric capacitance to strengthen the damping force, and simultaneously achieve load-independent energy extraction with a single inductor. Charge recycling is realized by adjusting extraction time, and optimized through a m...
Power-Efficient Hybrid Energy Harvesting System for Harnessing Ambient Vibrations Chamanian, Salar; Çiftci, Berkay; Ulusan, Hasan; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01) This paper presents an efficient hybrid energy harvesting interface to synergistically scavenge power from electromagnetic (EM) and piezoelectric (PE) sources, and drive a single load. The EM harvester output is rectified through a self-powered active doubler structure, and stored on a storage capacitor. The stored energy is then transferred to the PE harvester to increase the damping force and charge extraction. The total synergistically extracted power from both harvesters is more than the power obtained ...
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...
Performance Enhancement of the Single-Phase Series Active Filter by Employing the Load Voltage Waveform Reconstruction and Line Current Sampling Delay Reduction Methods Senturk, Osman S.; Hava, Ahmet Masum (Institute of Electrical and Electronics Engineers (IEEE), 2011-08-01) This paper proposes the waveform reconstruction method (WRM), which is utilized in the single-phase series active filter's (SAF's) control algorithm, in order to extract the load harmonic voltage component of voltage harmonic type single-phase diode rectifier loads. Employing WRM and the line current sampling delay reduction method, a single-phase SAF compensated system provides higher harmonic isolation performance and higher stability margins compared to the system using conventional synchronous-reference...
