Abstract

A CMOS RF bandpass amplifier which performs both functions of low-noise amplifier and bandpass filter is designed for the application of 1.9 ㎓ RF front-end in wireless receivers. The positive-feedback Q-enhancement technique is used to overcome the low gain and low Q factor of the bandpass amplifier. The designed bandpass amplifier is simulated with HSPICE and fabricated using HYUNDAI $0.8\mu\textrm{m}$ CMOS 2-poly 2-metal full custom process. Under 3 V supply voltage, results of simulation show that the CMOS bandpass amplifier provides the power gain 23dB, noise figure 3.8 dB, and power dissipation 55mW.
