Description
Summary:Post analog-to-digital conversion correction is an active area of research in both academia and industry due to the high potential of positive impact in areas like Synthetic Instrumentation (SI), Software Defined Radio (SDR), RADAR, etc. This paper introduces a high fidelity Simulink™ based behavioral error model for time-interleaved analog-to-digital converters (TI-ADCs) to facilitate development of efficient post conversion correction algorithms for TI-ADCs. Theoretically TI-ADCs offer a technologically feasible and cost effective solution to the digitization of wide bandwidth analog signals. The contribution of the error model described in this paper solves a key obstacle in economical research and development in this area. In addition to the error sources associated with integrated high performance analog to digital converters ADCs, mismatched error sources affect the performance of time interleaved configurations.
