This paper describes a readout ASIC prototype designed by CHIPIX65 project, part of RD53, for a pixel detector at HL-LHC . A 64 × 64 matrix of 50 × 50 μ m2 pixels is realised. A digital architecture has been developed, with particle efficiency above 99.9% at 3 GHz/cm2 pixel rate, 1 MHz trigger rate with 12.5 μ s latency. Two analog front end designs, one synchronous and one asynchronous, are implemented. Charge is measured with 5-bit precision and the analog dead-time is below 1%. IP-blocks (DAC, ADC, BandGap, SER, sLVS-TX/RX) and very front ends are silicon proven, irradiated to 600-800Mrad.

Abstract
This paper describes a readout ASIC prototype designed by CHIPIX65 project, part of RD53, for a pixel detector at HL-LHC . A 64 × 64 matrix of 50 × 50 μ m2 pixels is realised. A digital architecture has been developed, with particle efficiency above 99.9% at 3 GHz/cm2 pixel rate, 1 MHz trigger rate with 12.5 μ s latency. Two analog front end designs, one synchronous and one asynchronous, are implemented. Charge is measured with 5-bit precision and the analog dead-time is below 1%. IP-blocks (DAC, ADC, BandGap, SER, sLVS-TX/RX) and very front ends are silicon proven, irradiated to 600-800Mrad.File in questo prodotto:
