Abstract
This article presents a 3 THz CMOS image sensor
(Tera-CIS). The sensor has a column-parallel readout (CPRO)
architecture that integrates an antenna-coupled pixel array and
CPRO circuit chains on a monolithic chip. The proposed compact
two-transistor (2T) pixel adopts a step-covered patch antenna
and a defected ground structure (DGS) to obtain sufficient
sensitivity and bandwidth. The step-covered patch antenna model
is developed to predict pixel performances precisely. The DGS
structure suppress
