The Common Emitter (CE) configuration is one of the three basic BJT (Bipolar Junction Transistor) configurations, along with the Common Base (CB) and Common Collector (CC) configurations. It is the most widely used because it provides high current gain, high voltage gain, and high power gain, making it ideal for amplifiers, switching circuits, oscillators, and […]

Voltage Multiplier Circuit Diagram, Working, Types and Applications
Voltage multiplier circuit forms a fundamental building block in high-voltage power supplies where the output voltage must be several times greater than the peak input voltage, yet the load current required is relatively small. Instead of using high-turn-ratio transformers which are large, expensive, and limited by insulation and core saturation constraints engineers often implement multipliers […]
Digital to Analog Converter (DAC) Block Diagram, Working, Types & Applications
Modern electronic systems rely heavily on both digital and analog signals. While microcontrollers, computers, and digital processors handle data in binary (digital form), most real-world signals such as sound, temperature, pressure, and voltage are analog. To bridge this gap, Digital to Analog Converters (DACs) are used. A DAC takes digital input (binary numbers) and converts […]
