Abstract
This article presents a terahertz (THz) source
system-on-a-chip (SoC) specifically designed for computational
imaging with a single-pixel camera (SPC). The SoC consists
of an 8 × 8 array of independent, frequency-unlocked THz
sources that together radiate maximum 10.3-dBm power at
0.42 THz. Each source pixel is composed of a fundamental
Colpitts oscillator, followed by a common-collector doubler and
an on-chip circular slot antenna. The THz power radiated
from the array can be modulated in space
