• This paper presents a complete base-band chain for WLAN applications in 1.4 V 90 nm CMOS. The chain consists of a 6/sup th/ order elliptic Gm-C 10/100 MHz filter and five VGA stages. The design is DC-offset free and uses optimized transconductance for linearity and low-voltage operation. Moreover, the integrators in the filter are compensated for losses through a frequency transformation. The IIP3 is 2 dBm at 13.5 dB minimum gain, while dissipating 13.5 mW.
