Electronics Oscillator[edit | edit source]

Electronics Oscillator is an electronics device that generates oscillation .

  1. Passive oscillator
  2. Active oscillator
  3. Variation

Passive oscillator[edit | edit source]

Passive oscillator can be constructed from

LC resonance tank circuit[edit | edit source]

RC phase shift[edit | edit source]

Active oscillator[edit | edit source]

Active oscillator can be constructed from class A Inverting amplifier with LC tune tank in the feedback . Class A Inverting amplifier has inverting amplification factor equals to -1

Class A Inverting amplifier + LC tune tank in the feedback[edit | edit source]


Class A Inverting amplifier + 3 stages of RC phase shift each has a phase shift of 60o in the feedback[edit | edit source]
