Class-D half and full-bridge power amplifiers (PA) finds their usefulness in wireless power transfer (WPT) blocks for a biomedical implant. This brief presents a 13.56-MHz wireless power transfer ...

Silicon MOSFETs-based medium-power (< 50W) Class-D amplifiers (CDAs) switching in the MHz range have gained popularity in recent years, which achieves better linearity thanks to a higher loop gain in ...
