15.36 Consider the Pierce crystal oscillator of Fig. 15.18 with the crystal as specified in Exercise 15.13. Let C, be variable in the range 1 pF to 10 pF, and let C, be fixed at 10 pF. Find the range over which the oscillation frequency can be tuned. (Hint: Use the result in the statement leading to the expression in Eq. 15.36.)
