A differential wideband LNA for a multistandard receiver has been designed and implemented in 0.18/spl mu/m CMOS. The circuit topology is a two-stage amplifier with active feedback. The input stage is a common-source stage with a common-drain stage in the feedback loop for impedance matching. Bandwidth enhancement with inductive shunt-peaking is used for maximizing the bandwidth. Measurements on the fabricated device show a power gain of 13.1 dB and a 3-dB bandwidth of nearly 7 GHz together… CONTINUE READING
