What is a Voltage amplifier?

A voltage amplifier is an electronic circuit designed to amplify an input voltage signal. This circuit takes a very weak voltage signal and increases it to a higher voltage level. Voltage amplifiers are widely used in various applications such as audio equipment, measuring instruments, and wireless communication systems.

Features:
・High gain: Amplifies the input voltage by a certain ratio.
・Wide frequency range: Can handle a broad range of frequencies from high to low.
・Linearity: Maintains a proportional relationship between the input and output signals, ensuring minimal distortion.

Application of Voltage amplifier

✅Audio amplifiers
Used to amplify audio signals and transmit them to speakers.
✅Measurement instruments
Amplifies weak signals for use in measurement and data acquisition.
✅Wireless communication
Used to amplify received signals to an appropriate strength for transmission in communication devices.
