Description

March 26, 2019

This module discusses three different architectures for sensing the voltage and current samples used to calculate the metrology parameters. These architectures involve using a SoC, metrology AFE, or standalone ADC. The advantages of the standalone ADC architecture compared to the other two architectures is discussed.
