Abstract
AbstractA K‐band low voltage, highly linear folded Gilbert cell mixer in 0.18‐μm CMOS is presented. An optimization technique been introduced which is particularly applicable to Gilbert cell type mixers. This technique has been experimentally verified with a down conversion mixer fabricated in a 0.18‐μm CMOS process. Utilizing PMOS devices in the transconductance stage and using a 2‐V supply voltage, the mixer can down convert from 24 GHz to 10 MHz with an input referred third order intercept of +20 dBm and a conversion gain of 2 dB. © 2007 Wiley Periodicals, Inc.
