Original Abstract

Presented paper deals with the practical aspects of implementation of test circuitry into CMOS design of an analogue-to-digital converter. Properties of the structure of switched-current mode are discussed for design-for-test. Since the switched-current structure changes the mode of operation of current copiers (switched-current memory cell), large fault coverage can be reached if creating proper design-for-test. As the example, analysis of an A/D converter is used, designed in switched-current technique, when sampling data. The contribution aims at problems concerned with controllability and observability of internal nodes. The models developed were utilized and SPICE simulations performed to verify theoretical proposals.
