    • A temperature sensor includes an open-loop delay line comprising plural delay cells and a multiplexer configured to select a first number of the plural delay cells; a delay-locked loop comprising plural delay cells and a multiplexer configured to select a second number of the plural delay cells; a clock coupled to an input of the open-loop delay line and to an input of the delay-locked loop; a detector having a first input coupled to an output of the open-loop delay line and a second input coupled to an output of the delay-locked loop; and a finite state machine configured to detect a transition in the output of the phase detector.
    • 温度传感器包括:开环延迟线,包括多个延迟单元;多路复用器,被配置为选择多个延迟单元的第一数量; 延迟锁定环路,包括多个延迟单元和被配置为选择所述多个延迟单元的第二数量的多路复用器; 耦合到开环延迟线的输入和延迟锁定环的输入的时钟; 检测器,其具有耦合到所述开环延迟线的输出的第一输入和耦合到所述延迟锁定环的输出的第二输入; 以及被配置为检测相位检测器的输出中的转变的有限状态机。
