摘要： A high-density deep trench capacitor array with a plurality of leakage sensors and switch devices. Each capacitor array further comprises a plurality of sub-arrays, wherein the leakage in each sub-array is independently controlled by a sensor and switch unit. The leakage sensor comprises a current mirror, a transimpedance amplifier, a voltage comparator, and a timer. If excessive leakage current is detected, the switch unit will automatically disconnect the leaky capacitor module to reduce stand-by power and improve yield. An optional solid-state resistor can be formed on top of the deep trench capacitor array to increase the temperature and speed up the leakage screening process.

摘要： The on-chip power supply noise sensor detects high frequency overshoots and undershoots of the power supply voltage. By creating two identical current sources and attaching a time constant circuit to only one, the high frequency transient behavior differs while the low frequency behavior is equivalent. By comparing these currents, the magnitude of very high frequency power supply noise can be sensed and used to either set latches or add to a digital counter. This has the advantage of directly sensing the power supply noise in a manner that does not require calibration. Also, since the sensor requires only one power supply, it can be used anywhere on a chip. Finally, it filters out any lower frequency noise that is not interesting to the circuit designer and can be tuned to detect down to whatever frequency is needed.
摘要翻译：片上电源噪声传感器检测电源电压的高频超频和欠压。通过产生两个相同的电流源并将时间常数电路连接到一个，高频瞬态行为在低频行为相当时不同。通过比较这些电流，可以感测到非常高频率的电源噪声的幅度，并用于设置锁存器或添加到数字计数器。这具有以不需要校准的方式直接感测电源噪声的优点。此外，由于传感器只需要一个电源，所以它可以在芯片的任何地方使用。最后，它滤除电路设计人员不感兴趣的任何较低频率的噪声，并且可以将其调谐到需要的频率。
