Abstract
In this paper we present a modeling methodology for fully integrated inductively degenerated cascode ultrawideband low noise amplifiers LNA with generalized filterbased impedance matching networks Our accurate analytical models capture the impact of device and passive component parasitics and transistor short channel effects to generate accurate designs Utilizing our methodology we are able to accurately generate an ultrawideband LNA in the 31–106 GHz frequency band using third and fifth order Chebyshev filters as input impedance matching networks The speed and accuracy of the proposed analytical model will facilitate rapid design space exploration for ultrawideband LNAs
