Read the Non-linear oscillator class notes.
For the non-linear oscillator circuit shown,
- Ra = 12 kΩ
- Rb = 18 kΩ
- R = 8.2 kΩ
- C = 1 μF
The op-amp output saturation levels are
VL+ = 5 V and VL- = 0 V.
The reference voltage is
VREF = 3 V.
For the base comparator, what are VTL and VTH? For the oscillator, what is the oscillation frequency?
