摘要

There is provided an oscillation circuit using a crystal vibrator including means A for obtaining an oscillation activation time Ts (Ts0) from an oscillation margin M by using a relational equation between the oscillation activation time Ts and the oscillation margin M or a relational graph thereof; means B for obtaining a relational equation between the oscillation activation time Ts and a load capacitance CL in an arbitrary driving current value Ios from the relational equation between the oscillation activation time Ts and the load capacitance CL, and the driving current value Ios; and means C for determining the load capacitance CL corresponding to the oscillation activation time Ts0 obtained by the means A, by using the relational equation between the oscillation activation time Ts and the load capacitance CL, which is obtained by the means B.
