Design of the power amplifier for ultrasonic transducer excitation is presented. We assumed that the amplifier output impedance will be significantly lower than the transducer input impedance. Therefore we suggest to used the transformer as voltage step-up and impedance matching element. The transformer influence on the ultrasonic transducer bandwidth and the power transfer efficiency are analy...

Abstract A hybrid switching amplitude modulator for class-E2 EDGE polar transmitters is proposed. To achieve both high-efficiency and high-speed, it consists of a wideband buffered linear amplifier as a voltage source and a hysteresis-controlled switching amplifier as a dependent current source. The novel linear amplifier has a high current driving capability of approximately 160mA with a bandw...

eGaN FETs have repeatedly demonstrated higher efficiency than MOSFETs in wireless power transfer amplifiers when operated over a wide impedance range using a ZVS Class D amplifier [1, 2, 3, 4, 5, 6, 7, and 8]. In this article we examine a method to further improve the performance of eGaN FETs by replacing the bootstrap diode of the high side gate driver with an eGaN FET that is driven synchrono...

The unprecedented instantaneous luminosity provided by the High Luminosity upgrade of LHC (HL-LHC) at CERN requires an Compact Muon Solenoid (CMS) electromagnetic calorimeter (ECAL). barrel region CMS ECAL will be preserved but operated a lower temperature and with completely new readout trigger electronics.
