Abstract :
We present a novel Antenna-less Regenerative Receiver (ARR) with subfW/√(Hz) noise equivalent power (NEP) and 10 GV/W responsivity for reflective (Stand-off) mode imaging applications. The proposed ARR eliminates previous needs of a separated antenna and an injection amplifier from the traditional SRR (Super Regenerative Receiver), and uses its existing passive resonance tank to capture backscattered radiation from the targeted object. As a result, the ARR can capture reflective images of plastic replica weapons at stand-off distances up to 3.5m with 30° off-incidence angle. Operating at 245 GHz, the ARR consumes only 0.036 mm2 of silicon area and 2.6 mW/pixel of power in 40nm CMOS technology.
