摘要： The present invention relates to a method for compensating temperature in a crystal oscillator including a capacitor array consisted of a first bank of unit capacitors each with low capacitance and a second bank of unit capacitors each with high capacitance. The method comprising the steps of calculating memory address that stores information about the capacitor array address in accordance with the temperature that is subtracted from present temperature by a temperature offset code; reading data from a memory address corresponding to remain bits excepted lowest bit when the lowest bit is 0 among the memory address; averaging data read from a memory address corresponding to remain bits excepted lowest bit and data of a memory address incremented by 1 from the memory address when the lowest bit is 1 among the memory address; transmitting data read from the memory address or averaged data to the first bank or second bank by comparing the memory address and temperature boundary code; and adjusting the capacitor array with capacitance corresponding to a present temperature by using data transmitted to the first bank or second bank.

摘要： A frequency tracking circuit and method comprising a master crystal oscillator circuit is used for frequency tracking between a handset and a base station comprising a calibration subsystem for taking a temperature measurement, a reference control circuit for determining a numerical value needed to align a handset frequency with a base station frequency, an adder for adding the numerical value to a previous numerical value determined by the reference control circuit, a latch for latching the output of the adder, and a low precision master crystal oscillator for clocking the frequency of the latch. The most significant bit from the latch is input into a phase/frequency detector for forcing a voltage controlled oscillator to track a desired frequency.
