چکیده

A fully integrated pulsewidth modulator for Class-S power amplifiers is presented. It consists of a triangular signal generator, a comparator and output buffer. The HBT BiCMOS design of PWM circuit is applied to the LTE frequency range, which converts digitally modulated 955MHz RF carrier with 2.87GHz sampling clock. This PWM shows an EVM 6.6%, a differential output voltage swing 1.35Vp-p with 62.7mA dissipating at 3.3V power supply.

A Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers

In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...

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...
