This paper presents the design and test results of a radiation tolerant PLL ASIC as part of the optical link ASICs in the Nuclotron-based Ion Collider Facility (NICA) front-end readout electronics. To obtain low DC leakage current and reduce dynamic mismatch, the charge pump uses two unity-gain feedback operational amplifiers to keep the output common mode voltage constant. The LCVCO employs a...
We demonstrate an RF receiver that achieves 25 ppm uncertainty in measuring the amplitude of a 1497 MHz sinosoidal signal in a 0.5 ms integration window. The receiver employs a direct digital sampling architecture. The signal comes from beam intensity monitoring cavities on the beamline of the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab. The signal strength,...
Diamond detectors are suitable for accelerator beam monitor owing to the better radiation hardness compared to silicon detectors. But the smaller deposited energy and larger band gap cause the decrease of signals, which brings difficulties to readout system. In this paper, a low noise electronics based on charge sensitive amplifier (CSA) reading out the signal of diamond microstrip detectors...

The High Luminosity upgrade of the LHC (HL-LHC) at CERN will provide unprecedented instantaneous luminosity of ~5 x 10$^{34}$cm $^{-2}$s$^{-1}$, leading to an average of 150-200 simultaneous collisions. This high instantaneous luminosity scenario presents a significant challenge for the detectors. The barrel region of the CMS electromagnetic calorimeter (ECAL) will be preserved but will be...
