Device
Low-noise receiver implemented in a 40-nm bulk CMOS process with fT / fmax = 300/270 GHz.
Spectrum
220 GHz
Novelty
A tri-coil gm-boosting network and an inductor-assisted differential noise-cancellation network are proposed that improve both gain and noise performance. The lossy-Gmax-core architecture ensures simultaneous gain and noise matching and further enhances the gain, achieving the lowest reported noise figure among CMOS RXs operating above 200 GHz.
Application
Ultrahigh speed wireless communication systems.
Performance
17.8 dB conversion gain (CG); 11.8 dB minimum noise figure (NF); -24.7 dBm input 1-dB compression point (IP1dB). 35.5 mW DC power consumption; a core area of 0.078 mm2 RX core area and a 0.2 mm2 total area.
