摘要：

In this paper we present a focal-plane array (FPA) for heterodyne imaging at 0.65-THz in a low-cost 0.25-mu m CMOS process technology. The 3x5 pixel array is fully integrated on chip and consists of differential patch antennas, NMOS square-law mixers, and 43-dB low-IF amplifiers. The NMOS square-law mixers are based on distributed resistive self-mixing and facilitate mixing well beyond the cutoff frequency of the technology. First 0.65-THz heterodyne imaging results are presented.
