Multistandard transceivers usually have high order low pass filters in their receiver chains. Different filter topologies may have various component variation tolerances and different output noise. In this work, three 6th order filter with different topologies are analyzed for use in multistandard transceivers. Filters are designed in 0.18 µm and 65 nm CMOS technologies and simu-lated using Cadence software. The results show, that the filter frequency response variation in integrated circuits does not de-pend on the filter topology. Simulation results also show that the Leapfrog filter topology has the smallest integrated output noise in the filter bandwidth and is most suited for low noise applica-tions.
