Abstract：This paper investigates the start-up conditions in Pierce CMOS crystal oscillator base
upon the auto-control principle . The effect of oscillator start-up conditions caused by crystal
circuit parasitics has been analyzed theoretically in detail. The result of theoretical analysis is
verified using Matlab, and the optimum inverter which can guarantee circuit oscillate reliably has
been designed for the 15Mhz crystal oscillator as an example. Finally, using Hspice simulation,
the correctness of the theoretical analysis is verified further.
