In a previous article, I have shown you how you can build your own switched capacitor voltage converter circuit using the...
Charge Pump Circuit - Getting Higher Voltage from Low Voltage Source
The situation is simple – you have a low voltage supply rail, say 3.3V, and you want to power something that needs 5V. This is...
Simple Curve Tracer Circuit: Tracing the Curve for Resistor, Diode and Transistor
Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s...
Simple H-Bridge Motor Driver Circuit using MOSFET
At the outset driving a motor might seems like an easy task – just hook the motor up to the appropriate voltage rail and it...
