Title:
【発明の名称】TCXO回路において修正温度補償信号を供給する方法および装置
Document Type and Number:
Japanese Patent JPH08506466
Kind Code:
A
Abstract:
A modified temperature compensation signal (110) is provided in a temperature compensated crystal oscillator (TCXO) circuit (100) in the following manner. A temperature dependent current generator (104) produces a temperature compensation signal (108) whose amplitude changes responsive to changes in ambient temperature. The temperature compensation signal (108) is scaled, based on a plurality of discrete frequency adjust values (212), to produce the modified temperature compensation signal (110).
