Abstract
In this work, we present a wireless energy-efficient
fully integrated amplitude shift k eying (ASK) transmitter (TX)
array at 220 GHz. Each TX cell consists of an oscillator, a modu-
lation switch, an on-chip antenna, and baseband amplifiers. The
oscillator uses a harmonic generation technique that is optimized
for maximum output power and efficiency. The ASK scheme
is used for data modulation and is implemented with a fast
switch that does not consume any dc power. Three of these TX
cells are cohe
