Abstract
The test method of 32 channel X-ray readout integrated circuit (ROIC) has been proposed in this paper. Large resistors and a voltage source with high accuracy are used to generate 32 channels of weak currents, which are injected into the ROIC. Some key parameters of ROIC such as linearity, uniformity, cross talk, dynamic range have been tested. This method helps to test ROICs performance and does not need any photodiode and any laser light, which is convenient and easy to be realized.
