“…The switch network is optionally used to route one analogue input signal up to eight discriminators inside the ASIC. The DACs are differential with a resistor string architecture [5] to guarantee their monotonicity. They can be individually programmed through a slow control interface compatible with the serial to parallel (SPI) protocol.…”

“…There is one DAC per channel and all DACs are individually programmed through a slow control interface compatible with the serial to parallel interface (SPI) protocol. The differential DAC is based on two single ended 9 bit DACs [6] driven by a digital decoder in order to produce the 1023 voltage steps. The ladder architecture of the DAC ensures the output monotonicity and exhibits a 10 bit resolution with a maximal dynamic range of 2.9 V. The absolute values of DAC differential and integral non linearity are both less 0.5 LSB (LSB ¼ UDAC $ 2:85 mV).…”

a b s t r a c tKM3NeT aims to build a cubic-kilometer scale neutrino telescope in the Mediterranean Sea based on a 3D array of photomultiplier tubes. A dedicated ASIC, named SCOTT, has been developed for the readout electronics of the PMTs: it uses up to 16 adjustable thresholds to digitize the signals with the multitime-over-threshold technique. Digital outputs of discriminators feed a circular sampling memory and a ''first in first out'' digital memory for derandomization. At the end of the data processing, the ASIC produces a digital waveform sampled at 800 MHz. A specific study was carried out to process PMT data and has showed that five specifically chosen thresholds are suited to reach the required timing precision. A dedicated method based on the duration of the signal over a given threshold allows an equivalent timing precision at any charge. A charge estimator using the information from the thresholds allows a charge determination within less than 20% up to 60 pe.

“…The other drawback is that the effective output resistance depends on the values of N c and N f , thus affecting the dynamic performance of the DAC. In 2006, to overcome the problems caused by the fine ladder, C. C. Chen and Y. Perelman [5][6][7] respectively proposed two similar circuit architectures: the ''Folded multi-LSB decided resistor string DAC'' and the ''Inverted ladder DAC''. However, very few previous studies have conducted a detailed discussion of the non-linear specifications of differential nonlinearity (DNL) and integral nonlinearity (INL).…”

“…2 Folded multi-LSB decided resistor string DAC Figure 1 schematically depicts the architecture of our previously presented ''Folded multi-LSB decided resistor string DAC'' [5,6]. It consists of an L -2 L decoder, a main-resistor string, a top sub-resistor string, a bottom subresistor string, and an analog multiplexer, where L is the number of bits of LSB decided.…”
