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 ...

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.

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.

Index Terms— Jitter, low-noise **oscillators**, noise, noise measurement, noise simulation, **oscillators**, **oscillator** noise, **oscillator** stability, phase jitter, phase-locked loops, phase noise, phase-noise simulation, voltage-controlled **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.
