Abstract :
In this paper, the noise performance of the conventional MMIC transversal filter is studied. The in-band noise performance related to filter topology and circuit parameters are examined by a two-section transversal filter. A noise figure approximation is also evaluated to characterize the filter noise performance. In order to show the usefulness of this approximation , a prototype MMIC filter centered at 2.5GHz with about 10% 3dB BW is developed and it is implemented based on a 0.18μm CMOS technology. The simulation results show a good agreement with theoretical noise figure approximation
