Abstract: A method is provided for detecting limit cycles in a sigma delta modulator having an output signal that varies over a series of time intervals. In this method a first value that is indicative of the level of the modulator output signal after a predetermined time interval is stored in a first memory, and a second value that is indicative of the level of the modulator output signal after a further time interval subsequent to the predetermined time interval is stored in a second memory. The first value stored in the first memory is compared with the second value stored in the second memory, and an output indicative of a tendency for limit cycles to be produced in the modulator output signal is provided in response to such comparison. Such a method is particularly advantageous for detecting limit cycles in a sigma delta modulator as it can be implemented in a straightforward manner and offers a very accurate limit cycle detection mechanism.
