The robustness of three-stage opamp compensation methods in the presence of capacitor uncertainty is investigated. Eleven compensation techniques are compared to find which one is more robust against MOSCAP nonlinearity. A state-space model has also been proposed to analyze the harmonic distortion for different compensation techniques.
Using MOSCAPs for compensation can reduce the area needed for their implementation. However; these capacitors are highly nonlinear and their value changes when the voltage across their terminals is changed. Different compensation topologies do not exhibit equal sensitivity to the time-dependent variation of MOSCAP compensation capacitors.
Eleven compensation techniques are compared to find which one is more robust against MOSCAP nonlinearity. A state-space model has also been proposed to analyze the harmonic distortion for different compensation techniques. Circuit level simulations are performed to confirm the accuracy of the proposed method for calculation of harmonics.
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.
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.
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. It is seen that for lower frequencies the second and third harmonic magnitudes are reduced considerably.
