We present LUCAS (Low power Ultra-low jitter Compact ASIC for SiPM), an analog front-end Silicon Photomultipliers (SiPM) targeting fast timing detectors in Time-of-Flight Computed Tomography (ToF-CT). features a very low input impedance preamplifier followed by voltage comparator. It is designed TSMC 65 nm low-power CMOS technology with supply of 1.2 V. Our first 8-channel prototype has been sent to fabrication and will be received August 2023. Post-layout simulations predict less than 40 ps...
This paper presents the design, implementation, and performance evaluation of LUCAS, a low-power, ultra-low jitter ASIC optimized for SiPM readout in Time-of-Flight Computed Tomography (ToF-CT) applications. Leveraging novel preamplifier design with low input impedance current-mode operation, LUCAS addresses challenges such as parasitic capacitance SiPMs high-speed detection requirements. The ASIC, fabricated TSMC 65nm CMOS technology, features eight channels an integrated comparator,...
<title>Abstract</title> This paper presents a novel design methodology for transimpedance amplifier (TIA) featuring low input resistance. The resistance of the proposed TIA is achieved through implementation various analog circuit techniques, such as regulated cascode (RGC) and flip voltage follower (FVF), further enhanced by advantages BiCMOS technology. A key characteristic its ability to maintain consistently impedance across high frequencies without exhibiting inductive behavior or...
