<p>There is disclosed a charge-packet generation circuit for generating a series of charge packets, the circuit comprising: an active electronic device whose output signal is dependent upon its input signal, whose output signal affects the size of said charge packets, and whose output signal is affected by 1/f noise in the active electronic device due to an effect of the 1/f noise on such dependence of the output signal on the input signal; measurement means operable to obtain a noise measure, being a measure of the effect of the 1/f noise on said dependence; and compensation means operable based upon said noise measure to influence, or control, operation of the circuit so as to tend to prevent the 1/f noise from affecting the size of said charge packets.</p> |
