| The differential amplifier stage of an op-amp is as shown below | Generally the electrical behavior of the ceramic material can be divided into two classes related toitsstability |
|---|---|
| Thus the differential amplifiers amplify the difference between two voltages measured with respect to a common reference | Film power capacitors are also called as Power film capacitors |
Since Q1 and Q2 emitters are connected together, the emitter of Q2 also gets pulled up by the positive input at the non-inverting terminal.
| Tantalum electrolytic capacitors are obtained in both the types of wet foil and dry solid | Here the ceramic acts as its dielectric and metal acts as its electrodes |
|---|---|
| The polycarbonate capacitors are also used for AC applications | The construction techniques and materials which are used for large power film capacitors are usually similar to those of the ordinary film capacitors |
The high input impedance and gain of an op-amp allow straightforward calculation of element values, allows accurate implementation of any desired filter topology with little concern for the loading effects of stages in the filter or of subsequent stages.
