10 Easy Op amp Oscillator Circuits Explained
In an op amp oscillator circuit, an op amp is configured with a resistor-capacitor feedback loop or a inductor-capacitor feedback loop, which triggers the op amp to go into an […]
100 °C to 1000 °C Thermocouple Temperature Meter Circuit
The post explains a simple op amp based thermocouple temperature meter circuit which can be used for measuring high temperatures in the range of 100 °C to 1000 °C, in […]
How to Use Diodes, Transistors, ICs as Temperature Sensors
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 […]
Match Transistor Pairs Quickly using this Circuit
In many critical circuit applications, like power amplifiers, inverters, etc it becomes necessary to use matched transistor pairs having identical hFE gain. Not doing this possibly creates unpredictable output results, […]
Ultrasonic Fire Alarm Circuit using Air Turbulence Detection
The simple ultrasonic fire alarm circuit explained below detects a fire hazard situation by picking up the variations in the surrounding air waves, or the air turbulence. The high sensitivity […]
