Abstract
As the core component of electronic circuits, amplifiers play a pivotal role in fields such as communications, medical care, audio processing, instrumentation, scientific research and military technology. However, the noise problem of the amplifier has a direct impact on the reliability and accuracy of the system, how to reduce the impact of noise is crucial. This paper aims to study and solve noise problems in amplifier design. The first part focuses on the design of operational amplifiers. By adjusting the circuit structure and introducing current mirrors, the noise of the input and output stages is successfully reduced and the amplifier performance is improved. The second part focuses on the design of instrumentation amplifiers, introducing kT/C noise elimination technology, chopper modulation structure solves the noise and aliasing problems in switched capacitor instrumentation amplifiers and improve performance.
