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).
Abstract translation: 在温度补偿晶体振荡器（TCXO）电路（100）中以下列方式提供改进的温度补偿信号（110）。 温度依赖电流发生器（104）产生温度补偿信号（108），其温度响应于环境温度的变化而变化。 基于多个离散频率调整值（212）对温度补偿信号（108）进行缩放，以产生修改的温度补偿信号（110）。
