Circuits and techniques are described for reducing the impact of environmental noise and interference on the output signal of a capacitive sensor. The output signal is sampled randomly in some situations by generating a random sampling instant within a fixed clock period. The sampling is performed by a sampling or demodulation circuit. The demodulation circuit may be part of a larger circuit with various components that operate based on a fixed period clock signal.
