Description
As the leading research platform of heavy-ion science in China, the heavy-ion physics and heavy-ion applications at the Heavy Ion Research Facility in Lanzhou (HIRFL) and the High-Intensity heavy-ion Accelerator Facility (HIAF) drive the development of new detector technology. A Monolithic Active Pixel Sensor (MAPS) has been designed in a 130nm process for HIRLF and HIAF. This MAPS can measure the energy deposition, the hit position, and the arrival time of the particle hit. As the critical component of this MAPS, a 14-bit 40MS/s regional pipeline ADC converts the analog energy and time signal from the pixels into digital data. It adopts the structure of SHA(sample-and-hold)-less and a first stage of 3.5-bit. Additionally, in order to improve the accuracy of conversion, bootstrapped switches, input offset storage technology, and the redundancy algorithm have been used in the design. With a power consumption of 138mW and an area of 1380μm×1300μm, this ADC can achieve the SFDR of 98.60dB, SINAD of 83.36dB, and ENOB of 13.56-bit.
