  • Patent number: 10503578
    Abstract: An on-chip TDDB degradation monitoring and failure early warning circuit for SoC. A control circuit module converts Q1 and Q0 signals into a switch state control signal and outputs the switch state control signal to a digital conversion module for TDDB performance degradation. A MOS transistor of a first MOS transistor circuit within the digital conversion module for TDDB performance degradation is in a stress state of a supply voltage, and a MOS transistor of a second MOS transistor circuit is in a non-stress state. The first and second MOS transistor circuits output a first frequency value and a second frequency value to the output selection module. The output selection module outputs the first frequency value from the digital conversion module to the counter B for recording, or outputs the second frequency value to the counter A for recording. The counter module determines the degradation level of TDDB performance.

  • Publication number: 20190326455
    Abstract: The technique introduced herein decouples the traditional relationship between bandwidth and responsivity, thereby providing a more flexible and wider photodetector design space. In certain examples of the technique introduced here, a photodetector device includes a first mirror, a second mirror, and a light absorption region positioned between the first and second reflective mirrors. For example, the first mirror can be a low-reflectivity mirror, and the second mirror can be a high-reflectivity mirror. The light absorption region is positioned to absorb incident light that is passed through the first mirror and reflected between the first and second mirrors. The first mirror can be configured to exhibit a reflectivity that causes an amount of light energy that escapes from the first mirror, after the light being reflected back by the second mirror, to be zero or near zero.
