This LNA achieved 11.83±0.97 dB gain, S11 below -8 dB, S22 below -13.3 dB, noise figure of 4.2~5.2 dB and smaller group-delay-variation ±13.8 ps form 21 to 27 GHz.

The current-sharing technique is adopted for reduce current and achieve low power. Because of the quality factor of inductor is higher than microstrip line, we only replace part of inductors to achieve the best chip area. We present LNA in TSMC 0.18 m CMOS technology. This LNA achieved 8.85±0.75 dB gain, S11 below -8 dB, S22 below -10.8 dB, noise figure of 5.5~6.8 dB and small group-delay-variation ±17.8 ps over 21-27 GHz. The result shows of power consuming 5.4 mW, and chip area is 0.799 mm2. The results show that the LNA is suitable for low power radar systems. Finally, we have presented the K-band CMOS receiver front-end in TSMC 0.18um CMOS process. It consists of a low noise amplifier and a sub-harmonic mixer and converted RF signal to IF of 10MHz. The front-end makes the use of quadrature coupler and Marchand balun to achieve the needed phase difference. The measured results show the RF-to-IF isolation is below -33 dB, the LO-to-IF isolation is below -39 dB, the LO-to-RF, and 2LO-to-RF isolation is below -46 dB. The measured conversion gain at 24 GHz is 16 dB and the 1-dB gain compression point is -27 dBm. The measured RF port return loss over 21-27 GHz is below -10 dB and the LO port return loss at 12 GHz is below -10 dB. The measured phase difference of IFI and IFQ are 167.4° and 173.8°, respectively. The total power consumption is 47.7 mW, and chip area is 2.25 mm2. Yo-Sheng Lin 林佑昇 學位論文 ; thesis 105 en_US |
