Simple Audio amplifier Using Transistors
Construct a basic audio amplifier utilizing transistors. While integrated circuit (IC) designs are available for this purpose, the intention is to use transistors to gain practical knowledge about their amplification capabilities. The article "Amplifier Basics - How Amps Work (Intro)"...
TYPICAL TRANSISTOR CIRCUIT
This is a silicon transistor circuit showing typical voltage values. When the forward base/emitter voltage is 0.6 to 0.7 V, the transistor is silicon. Germanium transistors will have a forward base/emitter bias voltage of 0.2 to 0.3 V. This is...
Direct Coupled Discrete Astable Multivibrator circuit
This flip-flop circuit functions as a free-running astable multivibrator, where the bases and collectors of both emitter-biased transistors are directly coupled. The switching action is facilitated by a capacitor in each emitter circuit, resulting in the generation of triangle waves...
Quick On-Board Junction TesterCircuit
Acoustic check of transistor and diode junctions. Also suitable as a continuity tester. Short circuits or broken PCB tracks can be easily recognized.
The acoustic check of transistor and diode junctions is a method used to assess the functionality of these...
Transistor Circuits
It had been a little over a decade since the invention of the transistor when this article appeared in the August 1959 edition of Popular Electronics. Transistors were still a mystery to many, including engineers, technicians, and hobbyists. Author James...
Economical Transistor Radio
The schematic diagram illustrates an audio stage utilizing a common-collector circuit. This configuration does not dampen the tuned circuit; rather, it enhances its response, resulting in improved sensitivity and selectivity. Due to the low supply voltage, the subsequent audio amplifier...
Low Cost Amplifier Circuit Using Three Transistors
The operation and circuit diagram of a low-cost amplifier utilizing BC107 and BC148 transistors are explained in detail.
The low-cost amplifier circuit employs two types of transistors, BC107 and BC148, which are commonly used for their favorable characteristics in audio amplification...
Video Amplifier
The video amplifier illustrated in the diagram represents a well-established design that is simple yet highly effective. However, there is a risk of damaging the transistors if the potentiometers, which control black level and signal amplitude, are set to their...
microcontroller Why this transistor logic as switch is not working
The remote control of an RC car was modified by extending wires from the backward, forward, left, and right switches. Grounding any of these wires completes the circuit and sends a signal to the car. The intention is to close...
