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(More)
An OFDM capable Doherty PA is implemented in 90 nm CMOS with integrated quadrature hybrid and impedance transformer. The two amplifiers are optimized to minimize AM-PM distortion. The PA achieves 25 dBm Psa, using 1.4 V supply with 24% PAE, and operates over 1 GHz of frequency range (from 4 GHz to 5 GHz). 3 dB to 6 dB back-off from P<sub>1dB</sub> is(More)
