A power amplifier (PA) is a key part of the RF front-end in transmitters for a local broadband network. Today, commercial PAs are made of III-V HEMT and HBT technology with excellent results. An integrated system-on-chip power amplifier circuit using CMOS technology for cost-effective and spectrum-efficient high-speed wireless communication presents major challenges because power amplifiers hav...

In this paper, an adaptive hysteresis band current controller is proposed for active power filter to eliminate harmonics and to compensate the reactive power of three-phase rectifier. The adaptive hysteresis band current controller, proposed by Bose [An adaptive hysteresis band current control technique of a voltage feed PWM inverter for machine drive system, IEEE Trans. Ind. Electron. 37 (5) (...

In this paper, class DE inverter with second order constant K band-pass filter is proposed. In the proposed inverter, the band-pass filter is used instead of the resonant filter in class DE inverter presented at the previous papers. By using band-pass filter, two important results can be gotten. One is the sensitivity of the output voltage to the operating frequency is suppressed by using band-...
