This paper describes the theoretical analysis and performance of a 2.4㎓ bulk-driven downconversion mixer, where the LO signal is input via the bulk. A mixer core designed with a 0.18$\mu\textrm{m}$ CMOS process is able to operate under 0.8V∼1V supply voltage. The RF, LO, and IF port frequencies are 2.45㎓, 2.4㎓, and 50MHz, respectively. The measurement results exhibit conversion gain of -1.8㏈, l㏈ compression point of -17㏈m and IIP3 of -4㏈m with 0㏈m LO power. The power consumption is as small as 4mW.
