This work presents the experimental results from the characterization of a high accuracy injection circuit to be used for in-pixel calibration of a large sensor matrix. The circuit provides a useful tool for precise calibration of the readout electronics of the pixel cell unit for both monolithic active pixel sensors and hybrid pixel detectors. In the latter case the injection circuit is particularly useful to test the functionality of the readout electronics already at the chip level, when no sensor is connected to the chip. Two injection techniques can be provided by the circuit: one for a charge sensitive amplification and the other for a transresistance readout architecture. The aim of the paper is to describe the architecture of the calibration circuit and to present the relevant experimental results of the system, which has been implemented in a 130 nm CMOS technology.
