Photoconductive Cell Construction and Working: Photoconductive Cell Construction and Working - Light striking the surface of a material can provide sufficient energy to cause electrons within the material to break…
UJT Circuit Diagram: UJT Circuit Diagram Operation : The Unijunction transistor (UJT) consists of a bar of lightly-doped n-type silicon with a block of p-type material on one side, [see…
Silicon Bilateral Switch: It might be convenient to think of a Silicon Bilateral Switch (SBS) as an SUS with a gate terminal, or as a low-current TRIAC. However, the SBS is…
Silicon Unilateral Switch: The Silicon Unilateral Switch (SUS), also known as a four layer diode and as a Schokley diode, can be treated as a low-current SCR without a gate…
SCR Applications Circuits: SCR Applications Circuits : An SCR circuit is stable when it operates correctly: switching on and off only at the desired instants. Unwanted triggering (also called false…
Bridge Tied Load Amplifier: All of the power amplifiers already discussed have been single-ended (SE): meaning that they provide power to a load that has one terminal grounded and the…
Audio Power Amplifier using IC Amplifier Driver: The LM391 integrated circuit Audio Power Amplifier using IC Amplifier Driver contains amplification and driver stages for controlling an externally-connected Class-AB output stage…
Common Source Power Amplifier Using an Op Amp Driver Stage: Basic Circuit Operation - The Class-AB MOSFET Power Amplifier with OP Amp Driver Stage circuit in Fig. 18-45(a) consists of…
