Abstract: A frequency oscillator includes a ring oscillator having N inverters coupled in series, where N is an odd integer equal to three or more. A first filter is coupled between an output node of a first of the inverters and an output line of the frequency oscillator. A second filter is coupled between an output node of a second of the inverters and the output line of the frequency oscillator.

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.
