초록

This paper presents the design and analysis of LNA-Mixer for 2.45GHz RFID reader. The LNA is implemented by PCSNIM method for low power consumption. The Mixer is implemented by using the Gilbert-type configuration, current bleeding technique and the resonating technique for the tail capacitance. The connection between the two designed circuits is made by active balun. This LNA-Mixer has about 22dB gain and 8.5dB Noise Figure for -50dBm input RF power, LO power is 0dBm, RF frequency is 2.45 GHz and IF frequency is 100kHz. The layout of LNA-Mixer for one-chip design in a 0.18-um TSMC process has $2.5mm{\times}1.0mm$ size.
