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. Al, biased by V^, drives current through R (10 ) and the load. A2 senses this current and controls Al. The 10-1 resistor and 0.05-/iF capacitor sets the frequency response of the circuit.
