To probe further, I made the circuit schematic in LTspice, first using generic op-amp and then TL074 sub-circuit. The generic op-amp result was very close to values obtained with mcp6044. The results of simulation with TL074.sub was more or less the same as I obtained with...
LTspice: Stability of Op Amp Circuits WATCH SERIES Sep 18 2017 We all know that feedback circuits can oscillate. We may even know some tricks of how to fix it. But wouldn’t it be nice if our simulation tool could show us exactly what is happening, and why?

The proposed guidelines are validated with LTSpice simulations and practical experimentation along with step-by-step design examples. Practical results are compared with earlier reported FOCO which shows higher frequency and larger amplitude for the designed FOCO at a comparable THD. The proposed ...

LTspice仿真调试 借助LTspice模拟一个自激振荡电路,并且通过仿真来让这个电路不再振荡: 仿真前的设置: 图1 瞬态彷真Transient设置 在进行运放的仿真时,我们都是通过瞬态响应观察,所以是在Transient里面进行设置,通常运放的自激振荡在很短的时间内就会观察到波形,将仿真时间设置为10ms,保证观察到尽可能多一点的波形,同...
在LTspice 的 Voltage-controlled Voltage Source 中,可以使用 Laplace (拉普拉斯) 变换对传递函数。通过构建电压源的微分方程式,仿真各种各样的等价模型。 用Laplace 仿真一阶低通滤波器 首先,在“Select Component Symbole” 对话框中选择 “e”,并将其放在电路图上。如下图 (图1) 所示: ...
I now placed the AD8630 in a test circuit to confirm the correct operation of the model: The op-amp test gave reasonable results. Complete control loop I then added the op-amp circuit and the MOSFET circuit together to make the complete control loop: ...
