Abstract :
A low-power analog channel selection filter achieving +45-dBV out-of-band IIP3, +99-dBV out-of-band IIP2, and 17-nV/V√(Hz) input-referred noise is described. The filter is designed for a WCDMA direct conversion receiver and draws 2.1 mA from a 2.7 V supply. A highly linear, low-noise, low-power transconductor is presented. The filter is implemented with opamp-RC technique and fabricated with a 0.35-μm SiGe BiCMOS process.
