Abstract :
This paper describes advances in the hardware design of a system for characterizing and investigating high-resolution sigma-delta analog-to-digital converters. This work is being done in the frame of a Ph.D. study program in electrical engineering at the TU-BS, focusing the characterization and modeling of such converters with the help of sinusoidal and the PTB Josephson waveform synthesizers. An effective resolution of 18-19 bits at a sampling rate of 64 kHz has been attained.
