ADC & DAC courseA/D and D/A Conversion Software Radio -Postgraduate CourseLucian Stoica Introduction A/D Converter parameters and performance comparation table D/A Converter parameters and performance comparation Circuit design of a 4 bit FLASH A/D Converter in 0.35 m CMOS technology Testing techniques of ADC’s and DAC’s References Data conversion provides the link between the analog world and digital systems and is performed by means of sampling circuits, analog-to-digital (A/D) converters and digital-to-analog converters. Nyquist-rate Converters: generate a series of output values in which each value has a one-to-one correspondence with a single input value. Operate at 3 to 20 times the input signal bandwidth. Oversampling Converters: -operate at typically 20 to 512 times faster than the inpu……
