Hi all!
How can I set up the amplitude of a wien bridge oscillator made like this?
Let's suppose that the bottom resistances are (from top to bottom) R1, R2 and R3.
We know that for oscillations to start and converge we need:
R1 / R3 > 2 (let's suppose 2.2)
(R1 || R2) / R3 < 2 (let's suppose 1.8)
But how can I managed the amplitude?
