Abstract :
This paper presents a K-Band Down-Conversion mixer which is implemented in 65nm CMOS process. The conversion gain, noise performance and linearity are improved by using current bleeding technique and inserting an additional resonating inductor at common sources. The minimum NF is 12.7dB and the maximum conversion gain is 4.1dB with IIP2 of 80dBm. Two identical passive baluns are integrated for RF and LO input signals, which demonstrate a performance of 9dB insertion loss.
