“…The discriminator block for the majority trigger mode is based on a differential discriminator and a 10-bit digital to analogue converter (DAC) designed for the SCOTT chip ( [13] and [14]). In order to maximize speed, the discriminator utilizes a multistage architecture followed by a digital restorer and a latch, as depicted in Figure 5.…”

A versatile and reconfigurable ASIC is presented, which implements two different concepts of low level trigger (L0) for Cherenkov telescopes: the Majority trigger (sum of discriminated inputs) and the Sum trigger concept (analogue clipped sum of inputs). Up to 7 input signals can be processed following one or both of the previous trigger concepts. Each differential pair output of the discriminator is also available as a LVDS output. Differential circuitry using local feedback allows the ASIC to achieve high speed (500 MHz) while maintaining good linearity in a 1 Vpp range. Experimental results are presented. A number of prototype camera designs of the Cherenkov Telescope Array (CTA) project will use this ASIC.

“…For charge measurement, there are several methods applied in the readout electronics of high energy physics experiments, such as analog peak detection adopted in [4][5][6][7], digital peak detection adopted in [8][9][10][11], Time Over Threshold (TOT) principle adopted in [12][13][14][15], and waveform digitization based on Switched Capacitor Array (SCA) adopted in [16][17][18][19]. The analog peak detection has a relatively large dead time and the resolution of SCAbased waveform digitization is limited with high input signal frequency.…”

High precision and large dynamic range measurement are required in the readout systems for the Water Cherenkov Detector Array (WCDA) in Large High Altitude Air Shower Observatory (LHAASO). This paper presents a prototype of 12-bit 40 MSPS Analog-to-Digital Converter (ADC) Application Specific Integrated Circuit (ASIC) designed for the readout of LHAASO WCDA. Combining this ADC and the front-end ASIC finished in our previous work, high precision charge measurement can be achieved based on the digital peak detection method. This ADC is implemented based on power-efficient Successive Approximation Register (SAR) architecture, which incorporates the key parts such as Capacitive Digital-to-Analog Converter (CDAC), dynamic comparator and asynchronous SAR control logic. The simulation results indicate that the Effective Number Of Bits (ENOB) with a sampling rate of 40 MSPS is better than 10 bits in an input frequency range below 20 MHz, while its core power consumption is 6.6 mW per channel. The above results are good enough for the readout requirements of the WCDA.
