Abstract

This paper demonstrates generalized code-selective filters for code-pass and code-reject signal processing at RF. A code-reject scheme using a quarter-wave ( \lambda /4 ) impedance transformation is also demonstrated to overcome tradeoffs of insertion loss (IL) and linearity compared to series band-reject N -path filters. A 45-nm CMOS SOI implementation consumes a power of 9.32 mW from 1 to 1.8-V supplies at the frequency of 0.35-1.1 GHz and the chip area is 1.73 mm². The measured transmit rejection is up to 22.6 dB with 4-dB IL. The in-band third-order-intercept point (IIP3) is up to 22.6 dBm and noise figure (NF) of 4-6 dB depending on the applied codes.
