1. An electronic frequency-comb detection system, comprising:
an electronic frequency-comb detector comprising:
a frequency-comb generator configured to generate a frequency comb reference signal, wherein the frequency-comb generator comprises a series of inverter stages; and
a heterodyne mixer;
wherein the heterodyne mixer is configured to use the frequency comb reference signal to downconvert received millimeter wave (mm-wave) and terahertz (THZ) frequency tones into an intermediate frequency (IF) signal.
