Mixed-signal circuitry, used for example in a digital-to-analog converter, comprises digital circuitry (120) and analog circuitry. The analog circuitry receives a digital control signal (TCK) and produces one or more analog signals in dependence upon the received digital control signal. The digital circuitry comprises a main clocked circuit (122), clocked by an applied clock signal (CLK), and having an output (Q) at which the digital control signal (TCK) is generated. The main clocked circuit (122) causes the digital control signal (TCK) to change selectively at edges of the clock signal (CLK). A dummy clocked circuit (124), also clocked by the clock signal (CLK), produces a dummy signal (DTCK) at an output (Q) thereof.
