A 5-GHz CMOS fractional-N frequency synthesizer with a delta-sigma modulator is designed in this paper. The frequency dividers are composed of an injection-locked frequency divider and a programmable divider. In consideration of low power consumption, we use an injection-locked frequency divider as the first stage prescaler. The loop filter is a second-order passive filter. The delta-sigma modulator...
In this report, the transparent conducting indium zinc oxide (IZO) films (60-220 nm) have been grown on hardness poly-carbonate (HPC) substrate without a post deposition annealing treatment. The direct current (dc) magnetron sputtering system was employed for the film deposition. The IZO alloy target (99.99% and 95% in purity and density, respectively) is composed of 90 wt.% of ln2O3 and 10 wt.% of...
The hydrogenated poly-silicon germanium (poly-SiGe:H) epitaxial film has been investigated by gold induced lateral crystallization (Au-ILC) technology on a-SiGe:H layer at 10-hr 350degC annealing temperature and 60-sccm hydrogen (H2) content. By this optimal condition, the growth rate by Au induced can be as large as 15.9 mum/hr. Due to low annealing temperature treatment (les 400degC) and large growth...
