Abstract :
This paper presents a complete base-band chain for current and emerging WLAN in 1.4V 90nm CMOS. The chain consists of a 6th order elliptic Gm-C 1/10/100MHz filter and five VGA stages. The design is DC-offset free and uses optimized Gm stages for linearity and low voltage operation. IIP3 is 2dBm @ 13.5dB minimum gain, while dissipating 13.5mW.
