Abstract
This paper presents an integrated reconfigurable terahertz source array which employs a new method of joint space/time modulation to perform 2-D scalable and wide-range beam steering without phase shifters in a lens-coupled radiation set up. The reconfigurable array circuit can he activated in a variety of ways and is capable of simultaneous multi-beam/-frequency radiation. The chip is implemented in a 22nm CMOS-SOI process with a total area of 2.3 x 2.3mm(2), consumes 21-62.5 mW power per cell from a 0.8 V supply voltage, and provides a total of 40°/43° 2-D scanning range at 230-GHz frequency.
