Talk:Ring oscillator
From Wikipedia, the free encyclopedia
A single inverter does not provide enough phase difference for the ring oscillator to oscillate (Nyquist criterion of stability)

[edit] Loop time matters
Given a sufficiently long connection between the output and input, a single gate structure will oscillate. For a TTL logic gate the rise time is only a few nanoseconds so it will take a couple feet of wire to create enough phase difference between in and out. —The preceding unsigned comment was added by 192.128.134.68 (talk) 21:03, 19 January 2007 (UTC).
