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.
Tighter line and load regulation, low quiescent current operation, capacitor-free and wide-range output capac itor specifications are some of the contradicting requirements in an which drive newer topologies and newer frequency compensation techniques. The objective of this paper is to provide LDO,
As it is seen, good agreement is seen between these two methods. The problem of harmonic generation when MOSCAPS are used as compensation capacitors becomes less severe at lower frequencies. To be able to verify it, we have listed the harmonic amplitudes when the input frequency is reduced in Table 8.
For example if a MOSCAP is used as a compensation element, the fluctuation of opamp's output voltage can affect the value of the capacitor and change the circuit behavior. If a MOSCAP is used instead of a MIM capacitor in an analog circuit three possible scenarios may happen.
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.
Effect of compensation capacitor uncertainty As comprehensively discussed in Ref. [ 36], PCDM MOSCAP requires an area approximately 30% of MIM capacitors. For the structures that use few numbers of opamps, the die area occupied for the implementation of the opamps is not very critical and replacing the MIM capacitors with MOSCAPs is not logical.
