ABSTRACT:
Segmented mixed signal circuitry comprising a plurality of analog segments is disclosed. Each analog segment is operable to perform a series of switching operations dependent on an input data signal. The circuitry is arranged to receive shaped clock signals provided in common for all segments, and to perform each switching operation in a manner determined by the shape of the common shaped clock signals. The circuitry is suitable for use in digital to analog converters (DACs).
