Abstract

A fully-differential, 16-path bandpass filter (BPF) is demonstrated with wide tuning range, high linearity for and wideband harmonic rejection. The reconfigurable filter and clock generation circuitry is fabricated in IBM 45 nm CMOS SOI. To cover a tuning range of one decade (250 MHz to 2250 MHz), a 16-path scheme eliminates harmonic aliasing component to 15th harmonic of the local oscillator. The BPF has a 3 dB bandwidth greater than 20 MHz and 0.9 dB insertion loss. The BPF also achieves high linearity with an out-of-band IIP 3 > 27 dBm and P1dB > 3 dBm. The BPF tolerates blockers to 9 dBm 1 dB desensitization point (B1dB).
