Amplifier

OverviewClassification of amplifier stages and systemsHistoryIdealPropertiesNegative feedbackCategoriesApplications

One set of classifications for amplifiers is based on which device terminal is common to both the input and the output circuit. In the case of bipolar junction transistors, the three classes are common emitter, common base, and common collector. For field-effect transistors, the corresponding configurations are common source, common gate, and common drain; for vacuum tubes, common cathode, common grid, and common plate.

Input Capacitance in Analog Circuits: How to Compensate for …

The mistake I have is that I assume the closed loop gain expression is 1/beta*something, but it assumes the Vin is from positive input pin of the above circuit strucutre. However, the Vin is from the negative pin from the above circuit structure. hence, the 1/beta closed loop expression cannot be directly applied.

Amplifier

By design these amplifiers cannot amplify DC signals as the capacitors block the DC component of the input signal. RC-coupled amplifiers were used very often in circuits with vacuum tubes or discrete transistors. In the days of the integrated circuit a few more transistors on a chip are much cheaper and smaller than a capacitor.

Is a Diode a Passive or Active Component Explained in Detail

Common passive components include resistors, capacitors, and inductors. According to this definition, a diode can be considered a passive component because it does not supply energy to a circuit and cannot amplify a signal. It only allows current to flow in one direction, which can be seen as a form of energy dissipation or …
