Abstract: A temperature sensing circuit includes a signal generation unit including a delay line and generating a source signal with a pulse width corresponding to a delay value of the delay line, a pulse width expansion unit configured to generate a comparison signal by expanding a pulse width of the source signal, and a change detection unit configured to sense a temperature change using a difference between the pulse widths of the comparison signal and a reference signal.

Abstract translation: 温度检测电路包括：信号生成单元，包括延迟线，并产生具有与延迟线的延迟值相对应的脉冲宽度的源极信号;脉冲宽度扩展单元，被配置为通过扩展所述延迟线的脉冲宽度来生成比较信号 源信号，以及变更检测单元，被配置为使用比较信号的脉冲宽度与参考信号之间的差来感测温度变化。
