A phase-shift oscillator is an oscillator circuit designed to generate a sinewave output. It operates with a single active element such as a BJT or an op amp configured in an inverting amplifier mode. The circuit arrangement creates a feedback from the output to the input through using an RC (resistor/capacitor) circuit arranged in a […]

Sine Wave Inverter using Bubba Oscillator Circuit
In this post I have explained how to make a simple sine wave inverter using bubba oscillator sine wave generator. The idea ws requested by Mr. Ritwik Naudiyal. Technical Specifications I am a 4th year B.Tech Student Electrical Eng. We are trying to make pure wave sine wave inverter using PWM and bubba oscillator for […]
Sine-Cosine Waveform Generator Circuit
The circuit discussed below is designed to generate precision sine and cosine waveforms, which are perfectly identical with their dimensions, but are 90° out of phase. There are a variety of applications which often demand a couple of sinewave frequencies which are of the identical frequency, but 90° out of phase. Simply put, a sine […]
How Blocking Oscillator Works
A blocking oscillator is one of the simplest form of oscillators which is able to produce self sustaining oscillations through the use of just a few passive and a single active component. The name “blocking” is applied due to fact that the switching of the main device in the form of a BJT is blocked […]
