VOLTAGE_PROGRAMMABLE_CURRENT_SOURCE
This circuit is a programmable current source in which op amp LT1102 (Linear Technology Corp.) is used in conjunction with LT1006 op amp. A1, biased by Vin, drives current through R (10Ω) and the load. A2 senses this current and controls A1. The 10-kΩ resistor and 0.05-μF capacitor sets the frequency response of the circuit.
