摘要： Embodiments of an apparatus for measuring the leakage current of capacitive components is taught. One embodiment includes a first stage amplifier configured to receive an input from a serially-connected capacitive component at an inverting input and a feedback resistor in a feedback path of the first stage amplifier. A resistance value of the feedback resistor is programmable based on an expected value of the leakage current and a corresponding voltage output.

摘要： Some embodiments include apparatus and methods to test a device having a driving layer and a sensing layer. A test signal is applied to electrodes of the driving layer in a capacitive load state, with a capacitive load applied, and in an ambient state, without a capacitive load applied. Measured values are obtained at the sensing layer for each state. The measured values are compared with threshold values. A report is generated when a measured value violates a threshold. In one embodiment, the driving layer and the sensing layer form multiple capacitive electrodes within a touch sensor. The measured values are related to mutual capacitance values of the touch sensor.

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： A power conversion device includes a main circuit unit (direct-current main circuit) that converts direct-current power into alternating-current power, and a control unit that controls the direct-current main circuit. The direct-current main circuit includes a voltage detector (detector) that detects a capacitor voltage and a discharge circuit that discharges energy accumulated in a capacitor. The control unit includes a detection circuit that estimates a capacitor voltage during a normal operation based on a voltage transmitted from the voltage detector in a state where the main circuit unit is disconnected from a power supply and that detects a sign that a short circuit fault occurs in the capacitor, and a control circuit that outputs a control signal for controlling the discharge circuit to operate when the control circuit receives a detection signal from the detection circuit.
