In the case of either over- or under-compensated probes, the compensation capacitor is adjusted until the waveform has nice, square edges. This usually takes only a very small fraction of a turn. Note that square or rectangular waves are used for probe compensation because they have both high frequency and low frequency components.

Which way to connect a capacitor?

I need to connect a number of decoupling capacitors and am confused about which way to connect. My web search has turned up a lot of warnings but nothing to clarify to a complete noob. The negative (shorter) leg (cathode) on the capacitor. Does that connect to the GND or to the 5v / 12v side? Thanks

Which way to connect a capacitor?

An electrolitic capacitor does have a + and a - connection. They are NOT called cathode and anode, as they do with diodes. The + connection goes to the point with the highest potential (VCC or +V)

How is Metallized Film Capacitor Winding Done?

Most DC application capacitors are made with Aluminium metallization, while AC capacitors are made with zinc, or more preferably zinc alloy. Among the latter, nowadays, heavy edge metallization is more prevalent. There are more varieties like tapered (sloped) metallization, segmented metallized films etc. One type uses aluminium metallization with heavy edge zinc

6 FAQs about [How to connect the side compensation capacitor]

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.

Why do op amps need a compensation capacitor?

In addition, a better understanding of the internals of the op amp is achieved. The minor-loop feedback path created by the compensation capacitor (or the compensation network) allows the frequency response of the op-amp transfer function to be easily shaped.

How does a compensation capacitor affect frequency?

It is observed that as the size of the compensation capacitor is increased, the low-frequency pole location ω1 decreases in frequency, and the high-frequency pole ω2 increases in frequency. The poles appear to “split” in frequency.

Which capacitance should be used in a compensator design?

It should be noted here that the value of the capacitance used in the compensator design must be the small signal value. Ceramic capacitors lose some portion of their capacitance as their biasing voltage increases. The MLCC capacitors which are used in this example have 22μF nominal capacitance.

How can a large effective capacitance be created with a smaller capacitor?

Since the pole ratio needs to be very large, CC gets very large ! Thus, a large effective capacitance can be created with a much smaller capacitor if a capacitor bridges two nodes with a large inverting gain !! ZIN =? Compensation capacitance reduced by approximately the gain of the second stage!

Does a capacitor connect to a 5V / 12V side?

The negative (shorter) leg (cathode) on the capacitor. Does that connect to the GND or to the 5v / 12v side? Small ceramic capacitors do not have a polarity, so they can be mounten either way. Electrolitc capacitors have markings for the minus (- connection) most times there is a coloured band on that side.
