AN2867 Application note
www.st.comThe harmonic oscillator family can be divided into two main sub-families: negative-resistance oscillators positive-feedback oscillators. These two sub-families of oscillators are similar for what concerns the output waveform. They deliver an oscillating waveform at the desired frequency. This waveform is typically
The Ring Oscillator
www.seas.ucla.eduThe Ring Oscillator R Ring oscillators are commonly used in many systems because of their wide tuning range, compact layout, and ability to generate multiple phases. These advantages over inductance– capacitance (LC) oscillators come at the cost of phase noise. The concept of an oscillator con-sisting of gain stages in a ring can be
