Abstract
A differential digital power amplifier to drive an RFID antenna with a sinusoidal output current with an RFID frequency which differential digital power amplifier comprises: a digital control section to output digital wave-forming bits to a first group of driver blocks and a second group of driver blocks wherein a switch between the source contact of a first source follower transistor and the source contact of a second source follower transistor to short circuit these source contacts to unload/load gate-source capacitances of a drain extended PMOS transistors with charge carriers used to load/unload gate-source capacitances of the drain extended NMOS transistors to reduce the driver current needed at gate contacts of the drain extended PMOS transistors and drain extended NMOS transistors.
