This article presents a D‐band CMOS envelope detector (ED) used for a wideband on‐off‐keying (OOK) receiver. The ED consists of an input balun and a differential common‐source pair. The input balun is designed in a low‐loss rat‐race coupler. The baseband output signal is taken at the common node of the differential pair while the carrier is simultaneously suppressed. The ED is fabricated in a low‐cost 65‐nm bulk CMOS technology. The measured average responsivity and noise equivalent power are 1.16 kV/W and 234 pW/Hz 1/2 , respectively, from 110 to 170 GHz. To demonstrate its high‐speed demodulation capability, the ED is employed as an OOK receiver along with an on‐chip D‐band amplifier. The receiver demodulates the OOK signal of up to 4 Gbps through the air channel over a distance of 0.11 m. Furthermore, an air‐channel transfer of high‐definition video signal complying with the SMPTE 292M standard is successfully demonstrated using the receiver.
