Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...
A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...
You can use the inherent capacitanceof an LED to make a seriesresonant boost circuit that can create avoltage large enough to light the LED.Depending on the color of the LED, youneed a voltage higher ...
