RC filters are the most fundamental signal-processing circuits in electronics. It uses a combination of a resistor (R) and a capacitor (C) to selectively allow or suppress signals based on their frequency. Despite its simplicity, the RC filter plays a crucial role in almost every electronic system, from basic audio amplifiers to complex communication and […]
A Hall effect transducer is a sensor that detects a magnetic field and converts it into a proportional electrical signal using the Hall effect phenomenon. It is widely used for current sensing, position sensing, speed detection, proximity sensing, and magnetic field measurement in industrial, automotive, and consumer electronic systems. Unlike conventional mechanical or contact-based sensors, […]
A TVS (Transient Voltage Suppression) diode is a specialized semiconductor device used to protect electronic circuits from high-voltage transients such as electrostatic discharge (ESD), lightning surges, and switching spikes. It responds extremely fast and clamps overvoltage to a safe level before they damage sensitive components. Modern electronic systems are highly sensitive to voltage spikes caused […]
This article explains clamper circuits from the ground up including their types, mathematical analysis, waveforms, working principle, differences, applications, and real-world design considerations. Clamper circuits are fundamental waveform-shaping networks used in electronics to shift the entire signal level either upward or downward without altering the overall shape of the waveform. Unlike clippers, which remove or […]
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 […]
Capacitors are fundamental passive components used in electronic circuits for energy storage, filtering, coupling, and timing. Among them, Non-polar or Non-polarized Capacitors hold a special place because they can operate with AC signals and DC voltages of either polarity. Their versatility and stability make them essential in audio systems, RF circuits, SMPS, industrial power systems, […]
