• Could a simple passive RC network without any transformers, inductors, switches, or non-linear components produce a voltage gain? • Wow the engineering world with your unique design: Design Ideas Submission Guide Well, it’s not “free energy,” however, yes, and can even use the same value resistor and capacitor in a ladder network shown in Figure 1 , although differing values also can be utilized. • Figure 1 Passive RC circuit using resistors and capacitors of the same value in a ladder network. • Of course, this isn’t of much use other than a curiosity, but it’s a fun circuit to build and play around with! • I built one with seven sections ( Figure 2 ) using an R of 10 kΩ and a C of 0.1 µF, then plotted the results. • Figure 2 A seven-section RC ladder network with an R of 10 kΩ and C of 0.1 µF.
