SH and TH circuits. Parameters and types of DACs, chip structures, application notes. Parameters and types of ADCs, chip structures, application notes. Self calibration, testability. Vf and fV converters, Df converters, digital measurement of time intervals, phase, frequency. Design using ADCs and DACs.
Learning outcomes of the course unit
The student is able to:
- define the basic blocks signal processing chain of ADC and DAC,
- define and explain the basic parameters of AD and DA converters,
- describe the static transfer characteristic of AD and DA converters and mark some static parameters in it,
- describe the basic blocks of AD and DA converters (S/H, T/H stages, filters, reference, etc.), as well as design of those stages,
- describe and explain the function of the various structures of AD and DA converters, as well as on the basis of given parameters to select and design the most appropriate structure for the application.
The subject knowledge on the Bachelor´s degree level is requested mainly design of analog and digital circuits and knowledge of analysis and signal processing.
