This is a Simple Voltage controlled current source with grounded source and load. This is a simple, precise voltage-controlled current source. Bipolar supplies will permit bipolar output. Configurations featuring a grounded voltage- control source and a grounded load are usually more complex and depend upon several components for stability.Voltage-controlled-current-source-with-grounded-source-and-load. In this circuit, accuracy and stability almost entirely depend upon the 100-0 shunt.
