340-GHz Signal Source Design with Integrated On-Chip Bondwire Antenna in 40-nm CMOS
Abstract— This work presents two 340-GHz signal source designs with on-chip antennas for terahertz (THz)
imaging applications. The first signal source (1st SS) adopts a triple-push oscillator topology to generate a
single-ended THz signal which is radiated out by a proposed on-chip high-gain bondwire antenna with
simulated antenna gain as high as 2.9 dBi at 340 GHz. The second signal source (2nd SS) is realized by a
proposed triple-push oscillator topology which can provide differential output without any additional balun
required. The differential output is radiated to the air by an on-chip differential patch antenna with simulated
antenna gain of -3.9 dBi at 340 GHz. These two signal sources are implemented in 40-nm digital CMOS
technology. The measured output frequency and the equivalent isotropically radiated power of the 1st SS and
2nd SS are 346 GHz and 336 GHz, and -17.1 dBm and -16.8 dBm, while only consuming 58.3 mW and 44.6
mW from a 1.1 V supply, respectively.
