Ep 13. Amplifier Circuits Using Op-Amps

Understanding Modern Electronics is an informative and educational television program that explores the inner workings of modern electronic devices and circuits. In season 1, episode 13, "Amplifier Circuits Using Op-Amps", the show dives into the world of amplifier circuits that use operational amplifiers, also known as Op-Amps.

The episode begins by introducing viewers to the concept of amplifiers and their importance in modern electronics. Amplifiers are electronic circuits that increase the amplitude of an input signal to produce a stronger output signal. They are used in a variety of applications, from audio amplifiers in sound systems to power boosters in telecommunications equipment.

The episode focuses on amplifier circuits that use operational amplifiers, which are highly versatile and widely used in modern electronics. Op-Amps are differential amplifiers that amplify the difference between two input voltages. They have very high gain and can be configured in different ways to achieve different types of amplifier circuits.

The episode then goes on to explain the different types of amplifier circuits that can be built using Op-Amps, including inverting amplifiers, non-inverting amplifiers, differential amplifiers, and operational transconductance amplifiers (OTAs). The show provides detailed explanations of each of these circuits, including the circuit diagrams, equations, and calculations involved in their design.

The episode also delves into the practical aspects of building amplifier circuits using Op-Amps, including choosing the right components, designing the PCB layout, testing the circuit, and troubleshooting common problems. The show provides demonstrations of these processes using real-world examples, including audio amplifiers and instrumentation amplifiers.

Throughout the episode, the show emphasizes the importance of understanding the principles behind amplifier circuits and Op-Amps, rather than just following a recipe. This understanding enables engineers and designers to build effective and efficient amplifier circuits that meet their specific needs.

Overall, "Amplifier Circuits Using Op-Amps" is an informative and engaging episode of Understanding Modern Electronics that provides a comprehensive overview of amplifier circuits using operational amplifiers. The show is suitable for both novice and experienced electronics enthusiasts and offers practical insights that can be applied to real-world electronic projects.
