Analysis of Negative Feedback Amplifier Circuit Based on Protel99se
Xing Guo-quan · Modern Electronics Technique · 2010
The open-loop and closed-loop amplifier circuits are analyzed.The Protel 99se simulation software is used to analyze the static working section,transient charachteristic and AC small-signal.The analysis shows that the negative feedback amplifier circuit can improve the circuit stability,reduce the nonlinear distortion and broaden the transmission bands of the circuit;and that the Protel 99se can provide a mixed emulational function for the advanced analog-digital devices and simulate the circuit comprised of many elements such as TTL,CMOS,BJT,etc.
