- ПубликацияТолько метаданныеImplementation of the interpolator for signal peak detection in read-out ASIC(2020) Shumikhin, V.; Atkin, E.; Azarov, D.; Bulbakov, I.; Ivanov, P.; Normanov, D.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич© 2020 IOP Publishing Ltd and Sissa Medialab.A prototype interpolator for signal peak detection in read-out ASIC is presented. It uses interpolation algorithm for finding additional points between ADC samples. This allows to increase an accuracy for signal peak detection. Behavioral models of interpolator for Spline and Lagrange algorithm were realized and compared. Interpolator was designed in 180 nm UMC MMRF CMOS process. It is based on a 6th order Lagrange interpolation polynomial. The interpolator ensures the accuracy of signal peak finding is less than 1.5 LSB of ADC at sampling frequency of 25 MHz and 200 ns peaking time of 2nd order shaper.

D.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич© 2020, Pleiades Publishing, Ltd.Abstract: The interpolator is designed to determine the maximum signal amplitude in the analog channel of a readout ASIC. The use of an interpolator allows to mitigate the requirements for the sampling frequency of an analog-to-digital converter built into the channel of the readout ASIC. Design process and test results of an interpolator unit implemented by means of a FPGA are described.
- ПубликацияТолько метаданныеDevelopment of Data Concentration Method and Its Implementation in a Radiation-Tolerant CMOS Application Specific Integrated Circuit(2021) Atkin, E.; Azarov, D.; Normanov, D.; Ivanov, P.; Samsonov, V.; Serazetdinov, A.; Shumikhin, V.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич; Серазетдинов, Артур Рафикович© 2021, Pleiades Publishing, Ltd.Abstract: The results of the concentration method development for the data coming from the detector integrated circuits, intended for the experimental facilities MPD and BM@N, are presented. Charged particle detectors at these installations are characterized by a high granularity and accuracy of the detecting equipment. That results in a large data volume and the need to transfer processed data at a gigabit rate. Therefore, ASIC of the data concentrator requires both a high integration and use of specific structure as well as circuit and layout to provide an increased radiation tolerance. A specific feature of the ASIC is its ability to operate in the actual radiation background of the experiments estimated by up to 100 kRad in terms of immunity to heavy charged particles. In order to approbate the method and solutions on improvement of the radiation tolerance, the design results of a prototype 65 nm CMOS ASIC for read-out the signals from two SAMPA front-end chips cards are described. ASIC is intended for data receipt, concentration and subsequent transmission at a rate of 2.56 Gbit/s over micro-coaxial cables of 1 m length.

The chip has a built-in digital signal processing system intended to calculate the maximum signal amplitude (input charge) and based on the principle of interpolation. Using interpolation allowed to calculate the maximum charge amplitude with an accuracy of 1.5 LSB at using a built-in 10-bit ADC having a maximum conversion frequency of 25 MHz and a shaping amplifier with a peaking time of 320 ns. The readout ASIC was designed in UMC MMRF 180 nm CMOS process.

The clock generator operates with a reference clock frequency of 10 to 50 MHz and generates an output signal ranging from 400 to 1800 MHz in 10 MHz steps. The clock generator has been approved in 28 nm CMOS technology of TSMC. The power consumption and chip area of the block are 1.5 mW and 80 × 80 μm2 correspondingly. A wide range of reference and output frequencies makes this block versatile in application. © 2022 IOP Publishing Ltd and Sissa Medialab.

- ПубликацияОткрытый доступImplementation of the deconvolution method for signal peak detection in read-out ASIC(2020) Atkin, E.; Azarov, D.; Ivanov, P.; Normanov, D.; Serazetdinov, A.; Shumikhin, V. V.; Аткин, Эдуард Викторович; Норманов, Дмитрий Дмитриевич; Серазетдинов, Артур Рафикович© Published under licence by IOP Publishing Ltd.An application of the deconvolution method for signal peak detection in read-out ASIC for GEM detectors is described. Instead of usage of the conventional analog or digital peak detector, deconvolution technique to define the signal maximum was studied. In this case the digital data coming from the ADC are processed by a digital filter that deconvolves according to the pre-determined transfer function of the analog channel. Such processing allows to identify the signal peak values and also to provide reasonable pileup rejection. That enables higher rates of the incoming signals and reduces the amount of lost data. Combined with the analog channel employing 10-bit 25 MHz sampling rate ADC and 250 ns time constant 2nd-order shaper, the designed deconvolution block maintains peak detection accuracy within 9 LSBs. Time resolution of peak separation is 4 ADC sampling intervals or 100 ns.
