NEGATIVE VOLTAGE GENERATOR
Every circuit needs perfect bias supply to perform well and some times. Integrated circuits or special components or output actuators need negative voltage. Everyone needs a negative voltage rail eventually, but most only have one rail supply. This project will show you how to build a negative voltage generator that runs off a single rail supply voltage! CONCEPT OF GENERATING NEGATIVE VOLTAGE But using an oscillator, some diodes, and an ingenious arrangement of capacitors, we will exploit an impact called capacitive coupling whereby a negative voltage near adequate to the availability voltage can be generated... from a single rail supply! CAPACITIVE COUPLING Capacitive coupling is an impact where a capacitor “attempts” to stay the voltage across its terminals constant. For example, if each side of a capacitor are at 0V and plate 1 is suddenly delivered to...
