Abstract

Abstract: The interference of harmonic aliasing in N-path band-stop filter is a common problem, resulting in higher requirements for its interferer-tolerant performance. Firstly, the harmonic transfer functions relating the input to the voltage sampled on the capacitor are derived using the adjoint network, which simplifies the calculation of the harmonic transfer functions. Then the complete harmonic transfer functions of N-path band-stop filter are derived which are verified by the simulation of the circuit. The influence of filter parameters on harmonic aliasing is analyzed in UMC110 CMOS technology. It is concluded that the aliasing interference can be effectively suppressed by appropriately increasing the number of paths or the capacitance. The simulation result shows, that the max harmonic folding of the filter can be controlled below -27 dB, which has good anti-aliasing effect when the channel number is 16 and the capacitance is 50 pF. A cascaded design scheme of N-path band-stop filter and pre-frequency-selected device is proposed to eliminate harmonic folding. The cut-off frequency should be less than N-1 times the central frequency of N-path filter.

Key words: N-path filter, band-stop filter, switch capacitor, harmonic, harmonic aliasing, adjoint network
