摘要
分析了一种由单运算放大器构成、电路中包含二个充放电回路的多谐振荡电路,并对振荡信号的波形和输出信号的振荡频率进行了讨论,得到了计算公式;对振荡电路进行了实验分析,测试结果说明了理论分析的正确性。
The astable multivibrator using single operational amplifer is analyzed in this paper, the electric circuit contains two charging circuits. Vibration signal profile and the output signal frequency is discussed. The formula of the oscillation frequency is obtained. The experimental analysis is also carried on to the oscillating circuit. The result of actual measurement has proved the correctness of the theoretical analysis.
