Digital Step Sine wave Generator Circuit

Last Updated on September 22, 2026 by Swagatam 2 Comments

digital sinewave generator circuit compressed

In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]

6 Useful Voltage Controlled Oscillator Circuit Explored

Last Updated on September 22, 2026 by Swagatam 9 Comments

VCO compressed

In this post I have explained how to build 6 useful voltage controlled oscillator circuits, using various op amps and integrated circuits. As the name suggests, a voltage controlled oscillator or a VCO circuit is an oscillator circuit whose output frequency can be controlled or varied through an adjustable control voltage input. This means, if […]

How to Use Diodes, Transistors, ICs as Temperature Sensors

Last Updated on January 23, 2024 by Swagatam 14 Comments

AD590 temp sensor

Normally we find thermistors being used as the sensor for detecting and monitoring temperatures in electronic circuits. However, ordinary semiconductor components like transistors and diodes actually work better than thermitors when it comes to detecting temperature changes. In fact, this feature happens to be one of the greatest drawbacks of semiconductor devices, whose working characteristics […]

Extended High Bass Effect from Small Speaker Box [Cross-Over-Filter]

Last Updated on May 15, 2026 by Swagatam 2 Comments

high pass

Bigger speaker boxes produce proportionately higher bass effect, this fact is know to all of us. However, bigger boxes are not only expensive, they can be cumbersome and bulky. How about having the very same high bass effect, that a bigger box would provide, from a much smaller and compact speaker enclosure? Sounds strange right? […]

DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]

Last Updated on July 5, 2025 by Swagatam 54 Comments

SG3524 boost converter compressed

A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or as a buck-converter to step-down a higher voltage DC to a lower voltage DC. The switched mode conversion ensures that the power transfer in the […]
