Founder’s Day Special Issue October 2017 Design & development of Application Specific Integrated Circuits (ASICs) for High Energy Physics Experiment instrumentation

The contemporary High-Energy Physics experiments deploy variety of detectors, having high density readout channels for precise measurement of various experimental parameters. In such scenario, low power, high packing density, integrated complex functionalities, large dynamic range, good linearity and high speed are formidable constraints on the design of frontend (FEE) and data acquisition (DAQ) electronics. The efforts have been made by Electronics Division, BARC to design & develop the full-custom Application Specific Integrated Circuit (ASIC) based FEE and DAQ electronics in 0.7 um CMOS, 0.35 um CMOS and 0.35 um SiGe BiCMOS processes in presence of these challenges and trade-offs. The recent ASICs developed in this direction are ANUSANSKAR, ANUSMRITI and ANUSPARSH ASIC chipset. This article discusses these ASIC design aspects, applications and field deployed results achieved so far.
