Abstract
For fully autonomous implantable or body-wo rn
devices running on harvested energy, the peak and average
power dissipation of the radio tr ansmitter must be minimized.
Additionally, link symmetry must be maintaine d for peer-to-peer
network applications. We propose a highly integrated 90
W
400 MHz MICS band transmitter with an output power of
20
W, leading to a 22% global ef ficiency—the highest reported
to date for low-power MICS band systems. We introduce a new
transmitter architecture based on
