摘要
Abstract
Transistors are nonlinear devices, which can produce nonlinear distortion in amplifier while amplifying signals.For weak nonlinear distortion, the expressions of total harmonic distortion (THD), the second-order intermodulation distortion (IM2), the third-order intermodulation distortion(IM3) and intercept point (IP3) are deduced.With the aid of software Multisim, we simulate transistor common-emitter amplifier, transistor common-emitter amplifier with resistor in emitter, differential amplifier and differential amplifier with resistor between emitters. The simulational results and theoretical analyses are almost the same.关键词
