A fully integrated CMOS receiver consisting of an LNA and a mixer has been designed and fabricated in IBM BiCMOS 7WL 180 nm technology. An on-chip balun loading the second stage of the LNA was implemented as well for single-to-differential conversion. The receiver was developed for high performance wireless local positioning systems and excellent experimental results were demonstrated: a conversion...
In this work we present a fully integrated BiCMOS RF-receiver. The receiver comprises an LNA and a mixer. The most challenging aspects of the design were the high gain and an extremely low noise figure specified by RESOLUTION. The target was to achieve an integrated LNA and mixer showing at least 25 dB voltage conversion gain and overall noise figure less than 4 dB under minimum power consumption...
This work demonstrates an integrated low noise, high gain receiver targeted for wireless local positioning applications. The receiver is implemented in a 0.18 mum SiGe BiCMOS technology. With a single ended input and differential output the receiver comprises a two stage bipolar low noise amplifier with integrated on-chip transformer for single to differential conversion and a double balanced mixer...
A 60 GHz SiGe HBT chipset for high speed wireless communication systems has been developed. The functionalities of LNA, up-converter, down-converter and PA have been realized with good performance. Design strategy, achieved results and comparison with state-of-the-art work will be presented. The work proves that single chip integration of the whole 60 GHz RF-frond-end will be possible using silicon...
A folded double-balanced mixer has been implemented in a 0.18 mum BiCMOS technology for wireless local positioning applications. Operating in the unlicensed ISM band centred at 5.8 GHz with a 150 MHz bandwidth and with a very low IF frequency band from 500 kHz up to 5 MHz, the mixer achieves 17 dB voltage conversion gain, 8.5 dB noise figure and input IP3 of - 6 dBm. The mixer power consumption is...
