Research of Isolated Amplifier
Abstract: Isolated Amplifier is an amplifier that isolates the electric between input circuit and output circuit. By choosing the appropriate isolation device the transmission signal can be transmitted, the interference can be suppressed, and the purposes of the circuit can be protected. This paper introduces a kind of optical isolated amplifier using linear optocoupler, and briefly introduces the design principle and design difficulties of the circuit, and the simulation and experimental waveforms are given.
Key Words: optocouple isolated amplifier, linear optocoupler
