- In this paper, we present a 4-stage traveling wave lownoise amplifier for UWB RFID (ultra-wideband radiofrequency identification). This LNA covers a frequencyrange of DC - 13 CHz. The circuit is implemented with0.I5pm GaAs PHEMT chips embedded in flexible LCP(liquid crystal polymer) substrate. In the frequency range,the gain of the LNA is better than IO dB, fluctuation of thegain is less than 3dB, its noise figure is less than 4dB, SI 1and S22 are around -10 dB.

Conference paper (peer-reviewed)abstract
- Advances of VLSI and packaging technologies enable condensed integration of an RF system in a single module, known as SoC and SoP. In order to find a better solution between SoC and SoP for RF systems and their sub-systems, it is needed to predict and estimate performance of each solution. In this paper, analytical equations for noise figure and gain of inductively degenerated common-emitter low-noise amplifiers in SoP/SoC are deduced as functions of passives and packaging parasitics. They hence enable designers to evaluate overall performance of each solution quantitatively. As well, influence of lossy packaging parasitics on LNA is also analyzed.
