Abstract: A clock generating device includes a first timing delay module, a multiplexer, and a second timing delay module. The multiplexer is electrically connected to the first timing delay module. The second timing delay module is electrically connected to the multiplexer. The first timing delay module generates a plurality of delayed clock signals based on a reference clock signal. The multiplexer outputs a first delayed clock signal and a second delayed clock signal, among the plurality of delayed clock signals, based on a clock generating signal. The second timing delay module generates an output clock signal based on the clock generating signal, the first delayed clock signal and the second delayed clock signal.

Abstract: A pulse generating apparatus capable of calibration and calibrating method are disclosed. The pulse generating apparatus includes a pulse generator and a delay detector. The pulse generator is configured to repeatedly generate a testing pulse. The delay detector is electrically connected with the pulse generator. When the pulse generator generates the testing pulse, the delay detector detects a feature value of the testing pulse at a plurality detecting time points, and calculates a calibration value according to the detected feature values. The delay detector outputs the calibration value to the pulse generator and the pulse generator adjusts the testing pulse according to the calibration value.

Abstract: A testing device includes a switch, a sensing circuit, and a control circuit. The switch is coupled to a power supply circuit, and the power supply circuit is configured to output a supply voltage to a device under-test via the switch. The sensing circuit is coupled to the device under-test, and the sensing circuit is configured to receive an input voltage from the device under-test and to output a sensing signal according to the input voltage. The control circuit is coupled to the sensing circuit, the power supply circuit, and the switch. The control circuit is configured to control the power supply circuit to stop outputting the supply voltage at a first time and to turn off the switch at a second time according to the sensing signal.
