同样,Voltage-controlled Voltage Source (VCVS) 也使用电阻来仿真 10 倍的非反相放大器。 Voltage-controlled Voltage Source (VCVS) 的增益设置为非常大的值 1T (10 的 12 次方)。OP07 的频带宽度 (BW) 为 0.6MHz,而运算放大器的频率并不是无限大的,故大于 BW 的信号不能发挥放大器的作用,...
3、当Vh为负时,动作电压为Vh、Vt构成的特殊函数(后面会讲) 故上述模型的语法定义意思为:当阈值电压为0.5V时SW的阻抗为1欧姆,其余情况为1兆欧姆。 值得注意的是,SW的阻抗不能为0,并且兆欧的单位是Meg,1M表示的是1毫欧 3、SW的仿真实例 Vh=0时, 从上图可以看出当控制电压V1大于0.5V时,SW开通,直接下拉...
LTspice Tip 1 – using the current-controlled current source (CCCS) and the voltage-controlled voltage source (VCVS) Let’s simulate the following, sim.asc (right click to save) We’ve added the 0V voltage source (which behaves like a wire so it doesn’t affect the circuit) named VIB...

In this example a PULSE function source is used to generate a 0V–1V triangle waveform with a 1ms period. Voltage Controlled Switch in LTspice The switch has three distinct modes of voltage control, depending on the value of the hysteresis voltage, Vh. If Vh is zero, the switch is ...
Voltage controlled current source with time. I can make a part that is a formula having many inputs, time, frequency, voltage, temp., current, etc and outputs almost anything. C carbonzit Well-Known Member May 17, 2011 #8 I think I got it. It runs. Now I'd like to find out ...
Now we go to LTspice. The next step is to check the Laplace transfer function by using a voltage-controlled voltage source or a behavioral voltage source configured with the Laplace transform equation that came from SapWin (Figure 4).
Topics include modeling transformers, defining variables and stepping through values in a component, piecewise linear functions in source modeling, and voltage and current controlled switches, and improving simulation speed.Agenda: :Transformers Evaluate user-defined electrical quantities Defining and stepping...
