    摘要: The present invention relates to a radiation-detecting device and an associated detection method. The detection device includes a scintillation crystal and an avalanche photodiode. The surface of the scintillation crystal is coated with a high-reflection layer. When ionizing radiation irradiates the scintillation crystal, the crystal emits luminescence, which passes through or is reflected by the high-reflection layer at least once within the scintillation crystal before it is received by the avalanche photodiode, generating a detection signal.

    摘要: An isolation cell having a test mode, connected between a first block and a second block, wherein the first block can operate in either a power-up mode or a power-down mode, comprises: an input terminal for receiving an input signal that is derived from the first block; an output terminal for outputting an output signal to the second block; a normal-sleep terminal for determining the isolation cell is operated in the power-up mode or in the power-down mode, and the logic level of the normal-sleep terminal is determined by the operation mode of the first block; and, a DFT-sleep terminal is for overwriting the logic level of the normal-sleep terminal when the isolation cell is in the test mode.
