Abstract :
A new quadrature mixer topology, utilizing cross-coupled transconductance stages for linearity improvement is presented. The fabricated mixer showed OIP3 of 129.6 dBmuV (resp. 133.8 dBmuV), input referred noise of 4.7 nV/radicHz (resp. 5 nV/radicHz) with current consumption of 3.8 mA (resp. 4.8 mA) at a 2.9-V supply voltage using a 0.5-mum BiCMOS process
