Abstract:

A pseudorandom clocking scheme for an N-path bandpass filter is presented, which lowers the LO leakage to the filter's input and output. Measurements of a 65 nm CMOS prototype from 100 MHz to 1.4 GHz demonstrate 15 dB out-of-band rejection, IP1dB of +0 dBm, in-band IIP3 of +22 dBm, out-of-band jammer tolerance of +11 dBm, and LO leakage improvement of 10 dB to 15 dB with magnitude ranging from -60 dBm to -80 dBm.
