Abstract: A control apparatus is provided that can provide high dynamic resolution and is suitable for inclusion within an integrated circuit. The control apparatus receives a demand signal representing a desired value of a measurand, and a feedback signal representing a present value or a recently acquired value of the measurand. The processing circuit forms a further signal a further signal which is a function of the demand and feedback signals. The further signal is then subjected to at least an integrating function. The demand signal, feedback signal or the further signal is processed or acquired in a sampled manner. The use of such sampled, i.e. discontinuous, processing allows integration time constants to be synthesized which would otherwise require the use of unfeasibly large components within an integrated circuit, or the use of off-chop components. Both of these other options are expensive.
