2.5 V passive CMOS mixer with 20 dBm P1 dB compression
نویسندگان
چکیده
A passive CMOS downconversion mixer with LO buffer is presented in 0.25 mm SiGe BiCMOS using a 2.5 V supply. With a 60 MHz RF signal input, measurements show that the conversion loss is 2.9 dB, the input-referred 1 dB compression point is 20 dBm and the inputreferred noise is 2146.8 dBm/Hz. Compared to conventional NMOS mixers, the 1 dB compression point is improved by 9.7 dB. The tradeoffs and the design of the LO buffer, which has a strong impact on the intermodulation distortion, are also presented.
