Combining PWM switch models with linear circuit-analysis software and math software creates a fully computer-based approach to obtaining and analyzing the transfer functions of dc-dc converters.

All circuits, analog or digital ... A second-order lowpass function with two poles has a generic transfer function (Equation 5). These results are useful in understanding what sensitivity equations ...

Enter the equation in the Value field ... Up to this point, we’ve shown how LTspice can implement a transfer function by using circuit elements and the Laplace transform. Examples shown have ...

In a previous article (“Circuit Dynamics for Design”), we reviewed some of the mathematical properties of transfer functions in the s-domain and how generally to find the open-circuit time constants ...

In the earlier article, we showed that the transfer function for the circuit in Figure 1 is: Figure 1 This is the generic op amp inverter circuit. Figure 2 Here is the classic operational amplifier ...
