Circuitry and a method for generating a set of output clock signals

Abstract

A circuitry for generating output clock signals with increasing phase delays comprises: an input receiving input clock signals with increasing phase delays, wherein the output clock signals are twice as many as the input clock signals; logic components connected in a loop with an output from a component connected as a first input to a following component, wherein the output is further connected as a second input to an oppositely positioned component; wherein each component receives the first, the second and a third input signal; wherein pairs of oppositely positioned components receive a common input clock signal and mask out the third input clock signal based on logic state of first and second input signals such that the outputs are phase shifted by 180 degrees; and wherein the circuitry outputs the output clock signals based on outputs from each component.
