Sorry to tease, but it'll be coming in 2026, promise :)

NOTE FROM ETHAN CROWDER: This is a simple square wave oscillator, with close to a fixed 50% duty cycle, that utilizes two CD4046 Phase Lock Loop ICs. Four potentiometer connections have been included for each IC, that allows very precise frequency control. I'v...

What is Resonance? Resonance is a phenomenon that occurs when a system is driven at its natural frequency, causing it to oscillate with maximum amplitude. In electrical circuits, resonance occurs when the inductive and capacitive reactances are equal, creatin...

LC Circuit Fundamentals An LC circuit consists of an inductor (L) and a capacitor (C) connected together. These circuits form the foundation of resonant systems and are central to understanding how the VIC operates. Components of an LC Circuit The Inductor ...

Quality Factor (Q) Explained The Quality Factor, or Q, is one of the most important parameters in resonant circuit design. It quantifies how "sharp" a resonance is and directly determines the voltage magnification achievable in a VIC circuit. What is Q Facto...

Bandwidth & Ring-Down Decay Understanding bandwidth and ring-down decay is essential for designing VIC circuits that maintain resonance under varying conditions and for predicting how the circuit behaves when the driving signal stops. Bandwidth Fundamentals ...

Voltage Magnification at Resonance Voltage magnification is the cornerstone of VIC circuit operation. At resonance, the voltage across reactive components (inductors and capacitors) can be many times greater than the input voltage. This is how the VIC develop...

What is the Electric Double Layer? The Electric Double Layer (EDL) is a fundamental electrochemical phenomenon that occurs at the interface between an electrode and an electrolyte solution. Understanding the EDL is crucial for modeling the behavior of water f...

EDL Capacitance in Water Calculating the actual capacitance of a water fuel cell requires understanding how the Electric Double Layer contributes to the total capacitance. This page explains how to account for EDL effects in your VIC circuit calculations. To...
