1 What Is Op-Amp/Comparator?. by 0 and the output voltage will contain an error. An op-amp with a high open loop gain is desirable because
Refer to this note for guidance when using op-amps and comparators. a. Contents. 1. the error in the output voltage can be minimized by the high gain.
AN-1997 Error Amplifier Limitations in High Performance. ramp voltage at the PWM comparator such that a change in COMP leads to a commensurate change.
For the main PWM comparator, the use of an auto-zeroing comparator eliminates the control-loop offset between the error amplifier and the ramp-crossing level, thereby improving the overall system performance, especially at duty.
