Op amp gain nonlinearity
WebTypical op amps are not designed to be used as fast comparators, so individual gain stages will go into saturation when the amplifier output is driven to one of its extremes, charging the compensation capacitor and … Web10 de jun. de 2024 · Typically, the compensation is intended for closed-loop gains all the way down to the unity gain of voltage-follower operation. A subclass of op-amps come compensated for closed-loop gains above a value greater than unity, such as 10 V/V. Called decompensated op-amps, they offer faster dynamics than if they had been …
