For example, at 40 Hz, the Xc of the example circuit is just under 400 ohms. So the total complex impedance for the RC circuit is 1000 ... Once I got into AC, which wasn’t long from DC, ...
SPICE has been the mainstay tool for analog and RF designers for over 25 years. During that time, analog- and RF-circuit complexity has grown by several orders of magnitude while circuit geometries ...
Simulating a dc-dc converter in LTspice to model closed-loop voltage feedback. LTspice can be utilized to perform statistical tolerance analysis for complex circuits.
To try and install a more conventional ac-dc circuit would not only increase the PCB area, but would also be quite complicated. This increase in board area would also directly relate to the cost.
