A monolithic low noise high linearity LNA/mixer circuit for 2.5 GHz applications has been fabricated in IBM 47 GHz SiGe production process. The measured performance is 8 dBm input IP3, 1.6 dB NF and 12 dB Gain for a low noise amplifier (LNA), and 2.5 dBm input IP3, 7.5 dB NF and 14 dB gain for a downconversion mixer with a total current consumption of 26 mA(More)
Starting strategies were investigated for a three-phase single-stage power factor correction (PFC) converter. Starting process and mechanism of input over current was analyzed in detail. A lossy method was proposed and designed in which a resistor was connected in series with the filter capacitor to increase effective value of output voltage. Based on them,(More)
