Clock paths in mixed-signal integrated circuits are critical building blocks possibly determining the entire circuit performance. A precisely controllable clock phase is highly desirable e.g. for monolithic, ultra high-speed data converters with time-interleaving, i.e. digital-to-analog (DAC) and analog-to-digital (ADC) converters, to adjust the time-interleaved converter channels’ timing. More precisely, these converters use the means of analog multiplexing at the DAC outputs or analog demultiplexing at the ADC inputs, respectively. A broadband and low jitter clock path for frequencies up to 57 GHz is presented including 5 bit programmable phase interpolators at half input frequency with a phase delay resolution of about 1.25 ps realized in a 28 nm FD-SOI CMOS technology. A combination of current mode logic and CMOS logic is used in the proposed circuit.
