Integrated Circuit Operational Amplifier: Circuit Symbol and Packages - Figure 14-1(a) shows the triangular circuit symbol for an Integrated Circuit Operational Amplifier (op-amp). As illustrated, there are two input terminals,…
Amplifier Testing: Preparation - Transistor Amplifier Testing and other circuits should be tested in a methodical fashion; otherwise the results obtained may be useless. The circuit should first be carefully…
Capacitor Coupled Common Base Amplifier: A practical Capacitor Coupled Common Base Amplifier (using a plus/minus supply) is shown in Fig. 12-39. [Note the polarity of the input coupling capacitor (C1).]…
Differential Amplifier Circuit using Transistors: The Differential Amplifier Circuit using Transistors is widely applied in integrated circuitry, because it has both good bias stability and good voltage gain without the…
Direct Coupled Circuits: For economy, the number of components used in any circuit should be kept to a minimum. The use of direct coupling between stages is one way of…
Transistor Datasheet: To select a transistor for a particular application, the Transistor Datasheet provided by device manufacturers must be consulted. Most data sheets start off with the device type number…
Amplification in Transistor: Current Amplification in Transistor - We already know that a transistor can be used for current amplification. A small change in the base current (ΔIB) produces a large…
Transistor Voltage and Current: The Transistor Voltage polarities for an npn transistor are shown in Fig. 4-10(a). As well as conventional current direction, the direction of the arrowhead indicates the…
