Error amplifier output
WebThis process can take a long time. For example, an amplifier with a field-effect-transistor (FET) input, having a 1-pA bias current, coupled via a 0.1-μF capacitor, will have a charging rate, I/C, of 10 –12 /10 –7 = 10 μV/s, or 600 μV per minute. If the gain is 100, the output will drift at 0.06 V per minute. WebAug 22, 2024 · The output swing limitations of an amplifier also depend on the current level flowing through the output stage. The amplifier datasheet must be consulted to …
