15-1 Sine Wave Oscillators Ron Mancini and Richard Palmer 15.1What is a Sine Wave Oscillator? Op amp oscillators are circuits that are unstable — not the type that are sometimes unintentionally designed or created in the lab — but circuits intentionally designed to remain in an unstable ...

### Theory of Oscillator Design

When dealing with vacuum tube oscillators, particularly those employing pentodes, the approach taken in Section 1 might be found acceptable for mst engineering applications without much hesitation.

### "Sine Wave Oscillator"

Figure 2 demonstrates that, although two cascaded RC sections eventually provide 180° phase shift, the value of dφ/dω at the oscillator frequency is unacceptably small. Thus, oscillators made with two cascaded RC sections have poor frequency stability.

### Oscillators

Typically, the feedback block is frequency dependent - a resonator or filter or phase shift network. Considering a resonant circuit like a parallel RLC, the phase slope d d φ ω will set the frequency.
