THD Analysis in Closed-Loop Analog PWM Class-D Amplifiers
In this paper, we investigate the parameters affecting Total Harmonic Distortion (THD) and Power Supply Rejection Ratio (PSRR) in PWM Class D Amplifiers (CDAs) on the basis of linear models with feedback. From our mathematical analysis, we show that the THD of a PWM Class D amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...
متن کاملAnalysis and design of class E power amplifier considering MOSFET parasitic input and output capacitances
In this study, design theory and analysis for the class E power amplifier (PA), considering the metal oxide semiconductor field effect transistor (MOSFET) parasitic input and output capacitances, are proposed. The input resistance and capacitances cause non-ideal input voltage at gate terminal, which affect the specifications of the class E PA. In the proposed study, non-linear drain-to-source,...
متن کاملA Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
متن کاملPerformance Comparison for A4WP Class-3 Wireless Power Compliance between eGaN FET and MOSFET in a ZVS Class D Amplifier
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...
متن کاملBehaviors of EER Transmitter with Class-E Amplifier due to MOSFET Parasitic Capacitances
The class-E amplifier [1]-[11] is remarked as the next candidate of digital wireless power transmitters. Non-switching power amplifiers suffer from low power-conversion efficiency due to their inherent power loss in high back off area. Hence, switching power amplifiers such as class-D and E are remarked as a remedy for improving power-conversion efficiency and prolonging battery lifetime of por...
