High-Performance Analog/Mixed-Signal Characterization Techniques Agenda • fundamental underlying principles for successful high-precision mixedsignal/analog IP development • 24-bit Analog Front End (AFE) -what is it and what does it do? • IC design -best practices • basic lab set up and equipment -best practices • evaluation board -best practices • data analysis -best practices • measured results/lessons learned • conclusions fundamental underlying principles:first -high-precision/performance analog/mixed-signal IP must be proven/verified in silicon before being used in a product.second -a high-precision/performance analog/mixed-signal circuit (like a 24bit AFE) is very difficult to design, characterize and test and requires extreme attention to detail on all fronts.third -the initial evaluation of high-precision/performance analog/mixed-signal IP must be done by the people that designed it. Agenda• fundamental underlying principles for successful high-precision mixedsignal/analog IP development • 24-bit Analog Front End (AFE) -what is it and what does it do? • IC design -best practices • basic lab set up and equipment -best practices • evaluation board -best practices • data analysis -best practices • measured results/lessons learned • conclusions IEC energy meters are typically quoted as n(m) @ p% • where n is the nominal current • m is the maximum current • p is the percent accuracy for the meter -i.e. 5(500) @ 0.1% meters are required to meet the specified accuracy (p), from 5% of nominal (n) to maximum current (m)meter dynamic range is defined as the ratio of the maximum current to the minimum current:BUT, as stated above, the meter accuracy specification (p) applies over the entire meter dynamic range which leads to the following expression for the dynamic range of the meter's analog-front-end (AFE):
