Abstract
Phased arrays are widely used due to their low
power and small area usage. However, phased arrays depend
on the narrowband assumption and, therefore, are not suitable
for high-bandwidth applications. Emerging communication stan-
dards require increasingly higher bandwidths for improved data
rates, which results in a need for timed arrays. However, high
power consumption and large area requirements are drawbacks
of radio frequency (RF) timed arrays. To resolve these issues,
we introduce the first
