Q. What is Miller integrator ?
MILLER INTEGRATOR : Consider a basic RC circuit in which the opening of switch provides a sweep voltage.Yhe waveform generated by this basic circuit is not exactly linear,even if the ratio of the sweep voltage and the supply voltage is kept high.The linearity can be improved if the feedback arrangement , such as Miller sweep circuit is made with this. Feedback can be provided if an auxiliary variable voltage generator is introduced in such a way that variable voltage is always equal to the voltage developed across the capacitor.
