High-performance analog/mixed-signal characterization techniques

摘要

•high-precision/performance analog/mixed-signal IP must be proven in silicon before it is ever designed into a product. •successful characterization of high-precision/performance analog/mixed-signal IP is hard and requires extreme attention to detail on all fronts. •best practices in each of the following areas have been presented: test chip design-lab set up and equipment-evaluation board design-data analysis •measured data from a 24-bit AFE for power metering (using the presented techniques) was presented — measurements indicate >20-bit dynamic range (un-averaged) and > 23 bit dynamic range (with averaging)
