Power Diodes and Rectifiers

1. Normal Rectifier Circuit

Introduction We know that small signal diodes are used in applications of power rectifiers, switching circuits and snubbing the small duration waveforms. Signal diodes conduct electric current solely in one direction from anode to cathode, this is the most important property used in converting alternating current to direct current. This…

Morse Code Symbols

Introduction The first successful system of electrical communication was the telegraph, which was invented by Samuel F.B. Morse in the year 1832. The telegraph operators used a code of clicks to send the messages. If the key pressed for a short time it is the Morse code called ‘dot’ and…

Non-linear Op-Amp Circuits

Astable Multivibrator Using Op-Amp

Introduction Operational amplifiers, along with linear circuits, are also vastly used to configure non-linear circuits, i.e. circuits whose output exhibits non-linear change with respect to the change in the input. These circuits are commonly known as switching circuits, whose output switches between positive and negative saturation voltage levels. Most popularly…

Signal Diode Tutorial

signal diode

Introduction: Diodes are often used as straightforward rectifiers, as mixers in compounding the signals and as switches to open or close a circuit. Diodes in the mixers are utilized for detecting the signals and these diodes are typically referred as signal diodes. The simple and conventional application of signal diodes…

Operational Amplifier as Differentiator

Ideal Op-Amp Differentiator Circuit

Introduction An op-amp differentiator or a differentiating amplifier is a circuit configuration which produces output voltage amplitude that is proportional to the rate of change of the applied input voltage. A differentiator with the only RC network is called a passive differentiator, whereas a differentiator with active circuit components like…
