A low power area efficient 5 bit current steering DAC is presented. The proposed DAC is integrated to prototype the readout channel for muon chamber in CBM experiment. DAC was implemented with an area of 0.019 mm2 in the CMOS process using UMS MMRF 180 nm technology. This DAC has ultralow power consumption - 25μW. The measured differential nonlinearity (DNL) is better than 0.25 LSB, integral...

One of the main stages of blood and bone marrow cells recognition at the acute leukemia diagnosing is the leukocyte segmentation. The quality of cell separation methods in computer microscopy can be constrained by different exposure conditions which can in turn cause worse segmentation quality. Leukocyte segmentation efficiency based on the histogram method is considered in the paper.

The paper describes methodology of substrate noise isolation for ASICs implemented in the CMOS processes. Up-to-date CMOS technologies allow embedding the digital processing blocks into the same die as the readout analog part. This significantly improves the functionality and complexity of the readout ASICs. In fact performance of the precision analog circuits (e.g. charge sensitive amplifier,...
