Abstract :
A novel circulating shift register for switched-capacitor N-path filters is presented. The configuration affords a means of increasing the allowable discharge time for the shift register capacitors and eliminates clock feedthrough at the signal frequency. The shift register employs a simple 2-phase clock signal for any number of paths.
