去耦电容器的存在和可操作性测试
摘要：
一种电子设备(101)，包括：电源(110)；耦合到该电源的功率管理单元(102)；以及负载组(103a，103b，103c，103d)，功率管理单元包括：电压调节器块组(104a，104b，104c，104d)，每个电压调节器块分别耦合到负载组的关联负载，以允许从电源到该负载的功率传输。电子设备包括尖峰检测器块(106)，其耦合到每个电压调节器块，并用于检测来自电压调节器块的电压信号中的尖峰，以测试在电压调节器块的输出与关联负载的输入之间的去耦电容器(Ca，Cb，Cc，Cd)的存在和可操作性。
摘要（英）：

Electronic device (101) comprising a power source (110), a power management unit (102) coupled to the power source, and a set of loads (103a, 103b, 103c,103d), the power management unit comprising a set of voltage regulators blocks (104a, 104b, 104c,104d), each voltage regulator block being respectively coupled to an associated load of the set of loads for allowing power transfer from the power source to the load. The electronic device comprises a spike detector block (106), coupled to each of the voltage regulator blocks, and configured to detect a spike in a voltage signal from a voltage regulator block for testing the presence and the operability of a decoupling capacitor (Ca, Cb, Cc, Cd) between an output of the voltage regulator block and an input of the associated load.
