The compensation capacitor on the scope probe is then adjusted, using a non-metalic adjusting wand, to display a waveform with sharp …
6.2 OpAmp compensation Optimal compensation of OpAmps may be one of the most difficult parts of design. Here a systematic approach that may result in near optimal …
Capacitance: Choose a replacement capacitor with the same capacitance value as the faulty one especially if it was used in timing circuits. If the capacitor was used for voltage smoothing, larger capacitances will work as well. Voltage rating: Pick a capacitor with a voltage rating that matches or exceeds the original one. In most cases, a ...
Pole splitting is a phenomenon exploited in some forms of frequency compensation used in an electronic amplifier.When a capacitor is introduced between the input and output sides of the amplifier with the intention of moving the pole lowest in frequency (usually an input pole) to lower frequencies, pole splitting causes the pole next in frequency (usually an …
