Design of THz signal generation circuits using 65nm CMOS technologies

초록

In this paper, we present THz signal generation circuits in 65 nm CMOS technologies. All the designed circuits are verified by simulations. A push-push oscillator is designed for a THz signal generation, which has output frequency of 300 GHz and output power of -7.4 dBm. THz on-chip antennas are designed to radiate the signal generated by the oscillators. The simulation results of the designed CMOS loop antenna show the gain of 4.19 dB and radiation efficiency of 70 % at 260 GHz. In order to couple the oscillator to the waveguide, E-plane probe waveguide-to-micro-strip transition is designed to have the simulated insertion loss of 2.1 dB and bandwidth of 118 GHz around 280 GHz.
