sMDT Detectors ReadOut in 28nm technology A Fast Tracker analog front end for smalldiameter Muon Drift Tube (sMDT) detectors is hereby presented. The analog channel has been integrated in 28 nm CMOS technology and significantly improves stateoftheart sMDT readout systems thanks to a novel signal processing technique exploited to extract information from sMDT detectors speedingup the processing time and to limit fake events detection. The main idea is to implement a fast reset of all continuoustime analog stages that occurs just after the charge (i.e. event) detection. This has two main advantages for sMDT readout: fast processing and negligible signal corruption due to nonrelevant pileup signals. Nonetheless, the realization in 28nm bulkCMOS technology implies challenges for analog design but advantages in terms of speed, area occupancy and radiation hardness. The proposed analog channel occupies 0.03 mm2 and consumes 1.9 mW from 1 V supply voltage.

Design of HVCMOS Detectors in BCD Technology with Noise and Crosstalk Measurements This paper presents the design and implementation of a particle detector in a BipolarCMOSDMOS (BCD) 180 nm technology. The design has a substrate potential of xe2x80x94 50 V and supply voltage of 1.8 V. Size of the unit pixel sensor is  250times 50 mumathbfm2 . The chip consists of an array of  47times 6  pixels including the signal processing circuitry. The total chip area is  3.3 times 4.4 mathbfmm2 . The complete signal processing circuitry is hosted inside the diode sensor to achieve 100% fill factor. The chip consists of 106 inputoutput pads, including the pads for supplies viz. xe2x80x94 50 V, 0 V and 1.8 V. The measurement results are presented to validate the noise and crosstalk models of the designed detector. The comparison shows an average mismatch of 2.65  mumathbfV  for the crosstalk voltages in a range of 3000 to 7000 injected electrons. The circuit noise has an average mismatch of  1.23times 1010 mathbfV2mathbfHz  between the analytical and the measurement results for a frequency range of 100 kHz to 22 MHz. The analog processing circuitry provides a measured voltage gain of 33.3 dB at 100 kHz of input frequency.
