Hello there,
I cam across Wien Bridge Oscillators (attached below) but am having a hard time understanding why both the diodes are OFF at low signals?
My understanding says: when signal is low (i.e. negative), D1 will be ON and D2 OFF, and vice versa. Hence, the effective resistance will always be 22.1k || 100k.
Thanks,
