HDL-A based modeling of a current mode ADC

Mixed-mode simulations are increasingly recognized as useful methods for the validation of mixed-signal circuits before going on fabrication. HDL-A is one of the useful hardware description language devoted for analog and mixed-signal circuits. This paper attempts to validate the conversion algorithm of a multi-slope self-calibrated analog-to-digital converter by means of HDL-A. We show, for the analog part of the structure, the agreement between modeling and experimental results.
