Abstract :
A ultra-small distributed low noise amplifier was developed in a standard JAZZ 0.18-μm RF/mixed signal CMOS process. The 3-stage distributed amplifier occupies just 288 × 291 μm or 0.08 mm2 of die area, making it the smallest distributed amplifier reported to date. The circuit exhibits a relatively flat gain of 6 dB from 3.1 to 10.6 GHz with less than 0.5 dB ripple, with excellent input and output match of less than -12 dB and -25 dB, respectively. The noise figure is less than 5 dB to 14 GHz, with only 2.7 dB across 8-10 GHz, while the power consumption is about 22 mW.
