This circuit produces output current in strict accordance with the sign and magnitude of the control voltage, with no trimming required. Circuit accuracy and stability depend almost entirely on resistor R. Figure 4-36B shows dynamic response for a full-scale input step. Trace A is the voltage-control input and trace B shows the output current.
