All about Wien Bridge oscillators (2 - Oscillators)

Let's design a Wien Bridge oscillator. We'll cover everything you need to know, like how to get sufficient gain, design for a particular frequency, how to select components, and how to get the waveform to be sinusoidal and not a square wave.

Extremely clear explanation. Thank you

[@adanner]

You are welcome!

[@waitin4thateeeeeeeg]

Thank you for this good explanation! 🙂👍🙏🏾 Thank you 😊

[@yourparagon]

Absolutely spectacular! I felt like I only half-understood when my professor explained this, but you've helped me understand oscillator design much better with this playlist, thank you so much!

The world's best teacher thanks

The world's best teacher thanks sir

[@stefanopassiglia]

The best lecture on this oscillator. Thank you.

[@wagsman9999]

brilliant, seriously

[@khalidmsh-ks6mv]

sir, when we want to design a 1ghz oscillator how can we choose R and C please make a video

[@sarahbahgat8052]

Can you explain if I want to get a square wave from this sin wave that should I do ?

[@raoulselten9480]

you could choose a high value for R1 (say 100k) so that the gain of the circuit increases towards the rail voltage on the opamp. the opamp would saturate and your wave would become quite square. you could set the amplitude of the wave by controlling the rail voltage

Add a zero crossing detector that can be as simple as a single comparator
