One of the more restrictive design interrelationships for a two-stage amplifier is that with single-capacitor compensation and without emitter degeneration in the input stage, both the maximum time rate of change of output voltage and the unity-gain frequency of the amplifier are directly proportional to first-stage bias current. Hence ...

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.
reason, adding compensation capacitors can effectively reduce the influence of the track inductance on the signal. Once the compensation capacitor fails, it will reduce the transmission distance of the track circuit signal, making the system more prone to red light band faults and affecting the normal operation of the train.

A miller compensation capacitor decreases the value of the dominant pole for a two-stage Op-amp and propels the output poles away from the source. This phenomenon is named pole splitting, and it is an accustomed method in the design of operational amplifiers. Moreover, a miller compensation capacitor (Cc) is connected in parallel with the

The bottom plate of the compensation capacitor with 2C u at the REF node is constantly biased with V DD, while other capacitors will be switched between V DD and the global reference voltage V REF − G. Since this structure is a kind of ADC for output digitalization, the concept is also sometimes termed in-ADC computing. ...
All of the above compensation techniques [4]–[8] use Miller capacitors whose sizes depend on the size of the load capacitor. For larger loads the sizes of the Miller capacitors tend to in-crease. To alleviate this problem and further improve the band-width, no capacitor feedforward compensation (NCFF) [9], ac-
In single compensation, the capacitors are directly connected to the terminals of the individual power consumers and switched on together with them via a common switching device. Here, the capacitor power must be precisely adjusted to the respective consumers. Single compensation is frequently used for induction motors (Figure 4).

What is Compensation Capacitor? Definition of Compensation Capacitor: A capacitor whose purpose is to be connected either in series or in parallel with a coil in a circuit. The resulting LC circuit acts as a resonator at a certain frequency denominated as the resonant frequency of the circuit, in which the reactances of the capacitance and the inductance cancel each other out.
