Abstract :
Actual challenge for RF IC designers lays in the realization of high-quality integrated inductors. This paper introduces the concept of boot-strapped inductor and presents its application in a fully-integrated LNA with resonant LC preselect filter. The LNA achieves a power gain of 36 dB, a band-pass of 140 MHz and a noise figure of 2.0 dB at a working frequency of 1.8 GHz with a 3 V power supply
