Abstract:
A device for phase adjustment preset for an N-path filter comprising a logic block; a ring divider array creating a local oscillator drive for a mixer; the ring divider array comprising: a plurality of registers, each comprising: inputs S, R, D, and clock, and output Q; the plurality of registers comprising at least: a first register; a second register; and an Nth register; a preset control word; wherein the preset control word is applied to the logic block, the logic block providing input to each of the S and the R inputs of each the register; whereby a desired starting phase of the divider is controlled. A method includes defining a desired starting conditions; determining a control word from desired starting conditions; applying control word to logic block; applying a reset signal to logic block; and outputting values for each of S and R to each register.
