This paper presents a 245 GHz ASK modulator and demodulator capable of 40 Gbit/s operation. The design is based on 0.13 μm SiGe BiCMOS technology. The chip includes a 245 GHz SPST switch, a wide-band ...

Suboptimum SSB-PM envelope and phase detectors are considered and their performances above threshold are evaluated and compared. The results show a slight superiority of the phase SSB-PM over the ...
