Webcurrent boost stage. At DC and low frequencies the LM308 provides the signal path to the booster. In this fashion, a very high speed, high current output is achieved without … WebThey can range, depending on the op amp type, from a few femtoamperes (1 fA = 10 –15 A—one electron every few microseconds) to a few nanoamperes, or even—in some very fast op amps—one or two microamperes. Figure 3 shows how these currents can be measured. Figure 3. Offset and bias current measurement.
