Abstract:
Mixed-signal circuitry, operative to perform a series of operation cycles, comprising:n circuitry segments which together produce an analog output signal; a control signal generating circuit operable in each said cycle to generate, in dependence upon a digital input signal, a set of n segment control signals for application to respective ones of said segments to influence the produced analog output signal; and a morphing circuit which causes the n segment control signals to be applied to the n segments in at least two different orders at different respective times, said orders being such that at least one order differs from the next order by more than a starting ordinal position amongst the segments and that the changes in ordinal position of the segments brought about by the changes in order of application of the segment control signals are limited in number and/or magnitude relative to said number n of segments.
