Hi,
what are you using the polyphase filter for? Is it at the LO frequency, RF frequency or IF frequency? Or something else altogether? Anyway here's a paper you may want to read.
Behbahani, F, et. al., "CMOS mixers and polyphase filters for large image rejection", JSSC, vol. 36, no. 6, June 2001, pp. 873 - 887
cheers, Aaron
