6 FAQs about [Divided compensation capacitor]
Does a capacitor divider work as a DC voltage divider?
We have seen here that a capacitor divider is a network of series connected capacitors, each having a AC voltage drop across it. As capacitive voltage dividers use the capacitive reactance value of a capacitor to determine the actual voltage drop, they can only be used on frequency driven supplies and as such do not work as DC voltage dividers.
What is a frequency compensated voltage divider?
A frequency compensated voltage divider or attenuator is a simple two-port RC network providing a fixed voltage division ratio or attenuation over a wide frequency range and not just at dc. Such networks are used where the part of the circuit loading the voltage divider output is capacitive.
Why does a capacitive voltage divider always stay the same?
Because as we now know, the reactance of both capacitors changes with frequency (at the same rate), so the voltage division across a capacitive voltage divider circuit will always remain the same keeping a steady voltage divider.
What is the purpose of a compensation capacitor?
Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
Does a capacitive voltage divider network change supply frequency?
But just like resistive circuits, a capacitive voltage divider network is not affected by changes in the supply frequency even though they use capacitors, which are reactive elements, as each capacitor in the series chain is affected equally by changes in supply frequency.
What is a CC capacitor?
The Cc capacitor is connected across the Q5 and Q10. It is the compensation Capacitor (Cc). This compensation capacitor improves the stability of the amplifier and as well as prevent the oscillation and ringing effect across the output.
