Colpitts Oscillator using Op Amp: The Colpitts Oscillator using Op Amp circuit show in Fig. 16-4 is similar to the op-amp phase shift oscillator, except that an LC network is…
RC Phase Shift Oscillator Circuit Diagram: Figure 16-1 shows the RC Phase Shift Oscillator Circuit Diagram, which consists of an inverting amplifier and an RC phase-shifting network. The amplifier phase-shifts…
Voltage Follower Circuit Diagram: Direct-Coupled Voltage Follower - The IC operational amplifier can be employed for an infinite variety of applications. The very simplest application is the direct-coupled Voltage Follower…
Biasing Bipolar Op Amp Circuit: Biasing Bipolar Op Amp Circuit - Like other electronic devices, operational amplifiers must be correctly biased if they are to function properly. As already discussed,…
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…
Biasing Transistor Switching Circuits: Direct-Coupled Switching Circuit - When a transistor is used as a Biasing Transistor Switching Circuits, it is either biased off to IC = 0, or biased…
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…
