Abstract

A terahertz imager includes an array of pixel circuits. Each pixel circuit has an antenna and a detector. The detector is coupled to differential output terminals of the antenna. A frequency oscillator is configured to generate a frequency signal on an output line. The output line is coupled to an input terminal of the antenna of at least one of the pixel circuits.
