Abstract
A widely tunable RF LC-tracking filter is developed for tackling the odd harmonic mixing problem in wideband CMOS RF receivers. The filter is composed of two cascaded RLC tanks, where proposed programmable transconductor stages with built-in LPF are used. IIP3 of 127.7 dBmuV and input-referred noise of 20.1 dBmuV over signal band of 5.6 MHz are confirmed by measurements. The chip, fabricated in 0.18 mum CMOS process, occupies 2.8 mm2 and draws 34-120mA from a 1.8V supply.
