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...
In this work we report on the importance of electromagnetic analysis for the layout design of monolithic 60 GHz power amplifiers (PA) in SiGe HBT technology. To facilitate this, two different layouts of the same circuit architecture were investigated. The circuits were originally designed using the circuit simulator of Agilentpsilas ADStrade and realized in a high performance 0.25 mum SiGe BiCMOS...
In this work electromagnetic analysis and experimental verification of integrated microstrip transmission lines on silicon substrates have been performed up to 90 GHz. Several microstrip lines of different width and length have been realized on a five metal layer silicon substrate together with a commercial SiGe HBT process. All structures have been analyzed using a 2.5D electromagnetic simulation...
This work presents an active downconverter targeted for integration in 60 GHz high speed data communication RF front-ends. The designed downconverter has been realized in 0.25 mum SiGe BiCMOS technology with ft around 200 GHz. The downconverter consists of a single balanced mixer with an on-chip balun for differential to single ended conversion. High linearity and bandwidth are the main design goals...
This paper shows a fully integrated, ESD protected, low-power, low-voltage amplifier designed with a low-cost 0.18 mum SiGe technology. The amplifier achieves 11 dB gain, 8 dB noise figure at 23 GHz and 1 dB compression point of -18 dBm consuming 2.8 mW from the 0.7 V supply voltage. At this frequency the amplifier shows also 9 and 13 dB input and output return losses, respectively. Gain and power...
