Sub-THz OOK receiver for chip to chip data link

The chip to chip data link receiver is implemented with the non-resonant plasma wave detector at 250 GHz. The receiver is composed with on-chip patch antenna, stacked FET detector, and limiting amplifier. The stacked FET detector detect THz signal by non-resonant plasma wave transistor. The non-resonant plasma wave transistor is based on the broadband direct detection well beyond the cutoff frequency of the technology. The on-chip patch antenna is designed by top metal and the bottom metal of the technology. The bandwidth of receiver is limited by baseband limiting amplifier. The limiting amplifier is designed by 5GHz bandwidth and 40dB voltage gain. The receiver is designed for 10Gbps on-off keying (OOK) communication. Demodulation at 4 kbps has been verified because of the limited modulation frequency of THz source. The chip to chip data link with non-resonant plasma wave transistor is firstly implemented by CMOS process.
