Abstract
Abstract
The over 5 GHz available spectral space allocated worldwide around the 60 GHz band, is very promising for very high data rate wireless short-range communications. In this article we present two key components for the 60 GHz front-end of a transceiver, in 130 nm RF CMOS technology: a single-balanced mixer with high Conversion Gain (CG), reduced Noise Figure (NF) and low power consumption, and an LC cross-coupled Voltage Controlled Oscillator (VCO) with very good linearity, with respect to Vctrl, and very low Phase Noise (PN). In both circuits, custom designed inductors and a balun structure for the mixer are employed, in order to enhance their performance. The VCO’s inductor achieves an inductance of 198 pH and a quality factor (Q) of 30, at 30 GHz. The balun shows less than 1
o
Phase Imbalance (PI) and less than 0.2 dB Amplitude Imbalance (AI), from 57 to 66 GHz. The mixer shows a CG greater than 15 dB and a NF lower than 12 dB. In addition, the VCO achieves a Phase Noise lower than -106 dBc/Hz at 1 MHz offset, and shows great linearity for the entire band. Both circuits are biased with a 1.2 V supply voltage and the total power consumption is about 10.6 mW for the mixer and 10.92 mW for the VCO.
