ADI Multichannel Source Measurement Unit (SMU) Solution

A source measure unit (SMU) is widely used in the field of test and measurement. Examples of where it is used include I-V characteristic curve tests for semiconductors, parameter tests for various nonlinear devices or materials, and charge or discharge tests for various types of batteries. SMUs can operate in four quadrants of a V/I coordinate axis and can measure another type of signal while outputting one. The functions that used to be completed by multiple instruments can be now realized by a single SMU. Many well proven SMU products, commonly built with discrete devices, have been put on the market. These SMUs can realize a variety of current /voltage output combinations and accurate measurement, with the disadvantages of a complex structure and high cost. This article introduces an SMU reference design that is composed of an AD5522 master controller plus voltage/current amplifier stage.
