چکیده
DSRC provides high speed radio link between Road Side Equipment and On-Board Equipment within the narrow communication area. In this paper, a 5.8 GHz down-conversion mixer for DSRC communication system is designed and fabricated using 0.8 m SiGe HBT process technology and RF/LO matching circuits, RF/LO input balun circuits and IF output balun circuit are all integrated on chip. The measured performance is 7.5 dB conversion gain, -2.5 dBm input IP3, 46 dB LO to RF isolation, 56 dB LO to IF isolation, current consumption of 21 mA for 3.0 V supply voltage and the chip size of fabricated mixer is 1.9 mm X 1.3 mm.

Active mixers operating at 23 GHz are designed and fabricated in SiGe technology. An integrated diode linearizer is used to improve the linearity of the mixer. Measurement and simulation show excellent agreement. Typically, 10 dB double-sideband noise figure, 10 dBm IIP3 and 2 dB conversion gain are measured, featuring low noise and high linearity in a same design.

The neuron-MOS (neu-MOS) transistor, recently discovered by Shibata and Ohmi in 1991 [T. Shibata, T. Ohmi, International Electron Devices Meeting, Technical Digest, 1991] uses capacitively coupled inputs onto a floating gate. Neu-MOS enables the design of conventional analog and digital integrated circuits with a significant reduction in transistor count [L.S.Y. Wong, C.Y. Kwok, G.A. Rigby, in:...
