摘要
以LM386为重点研究了负反馈放大器自激振荡产生的原因及一般消除方法,着重就实际应用中因电源内阻或测试仪器仪表内阻引起的自激振荡的成因进行分析。
This paper studies the negative- feedback amplifier self- excited oscillation the cause and eliminate general, focused on practical applications for power or resistance test instrumentation resistance from the self-excited oscillation analysis of the causes and eliminate them.
