实用的PICmicro振荡器的分析与设计

资料介绍
There is a wealth of information written on the subject
of designing and analyzing oscillator circuits. Sources
range from academic and research papers to industry
generated application guides. It is a daunting task for
the embedded designer to work through all the avail-
able and sometimes conflicting information. All the
designer is really interested in is a simple set of rules
resulting in a reliable oscillator design that will work
despite crystal aging, deviations between devices,
temperature or voltage. The problem is the simple
Crystal Pierce Gate Oscillator (Figure 1) has a “simpli-
fied” model (Figure 2) that is anything but simple. None
of the values are fixed. Some vary with process, age,
temperature and voltage. Some components have a
nonlinear behavior with amplitude.
