|
In this paper, behavior of an oscillator under injection
of another signal has been investigated. Also, variation of output
signal amplitude versus injected signal phase variation, the effect of
varying the amplitude of injected signal and quality factor of the
oscillator has been investigated. The results show that the locking
time depends on phase and the best locking time happens at 180-
degrees phase. Also, the effect of injected lock has been discussed.
Simulations show that the locking time decreases with signal
injection to bulk. Locking time has been investigated versus various
phase differences. The effect of phase and amplitude changes on
locking time of a typical LC oscillator in 180 nm technology has been
investigated.
