CHAPTER 5 CLOCK GENERATOR
Figure 5-6. Examples of Oscillator with Bad Connection (1/2)
(a) Wiring of connection circuits (b) Signal conductors intersect
is too long with each other
(c) Changing high current is too near a (d) Current flows through the grounding line
signal conductor of the ocsillator (potential at points A, B,
and C fluctuate)
