Abstract
This paper presents a new type of flicker noise and
mismatch up-converting active m ixer with odd cascode switching
pairs that require lower switching frequencies. This requirement
relaxes the local oscillator (LO) s witching speed, which mitigates
the effect of flicker noise and IM2 due to parasitic capacitances. A
frequency-scalable LO generator is designed to eliminate delay ad-
justments between the slave LO and master LO signals for multi-
band operations, and a high crossing master LO drivin
