Abstract:

Diffusion models have recently revolutionized the field of image synthesis due to their ability to generate photorealistic images. However, one of the main drawbacks of diffusion models is that the image generation process is expensive. Large image-to-image networks have to be applied multiple times in order to iteratively optimize the …

HyFPCiM: A 65-nm 417-μW Error-Sensitivity-Aware FP8 Compute-in-Memory Macro

HyFPCiM: A 65-nm 417-μW Error-Sensitivity-Aware FP8 Compute-in-Memory Macro 150 150
Author(s): Gaurav Kumar K, Yatharth Agarwal, Kaushik Roy

Abstract:

This letter presents HyFPCiM, a 65-nm FP8 compute-in-memory (CiM) macro that enables sub-mW floating-point (FP) inference using error-sensitivity-aware FP partitioning (EAP). EAP maps exponent processing to a digital CiM (DCiM) path and mantissa accumulation to an analog CiM (ACiM), avoiding the power- and area-intensive adder-tree-based accumulation used in prior FP-CiM …

A 16-MHz CMOS RC Frequency Reference Achieving Accuracies of ±125 ppm From −40 °C to 85 °C and −560/+580 ppm After Accelerated Aging

A 16-MHz CMOS RC Frequency Reference Achieving Accuracies of ±125 ppm From −40 °C to 85 °C and −560/+580 ppm After Accelerated Aging 150 150
Author(s): Runtao Huo, Weihao Jie, Yiwen Zhang, Honglan Jiang, Hui Wang

Abstract:

This article presents a low-power, high-accuracy CMOS RC frequency reference featuring a capacitively modulated RC time constant (CMT) generation and a die-to-die error removal (DDER) technique for precise frequency generation with a low-calibration cost. Unlike resistive trimming, the temperature dependence of the on-chip resistor is compensated by a $\Delta \Sigma $ …

A 0.5-/0.95-dB NF, 50-/25-Ω Configurable CMOS Front-End ASIC for the Readout of Liquid Argon Calorimeter in the LHC

A 0.5-/0.95-dB NF, 50-/25-Ω Configurable CMOS Front-End ASIC for the Readout of Liquid Argon Calorimeter in the LHC 150 150
Author(s): Mietek Dabrowski, Filip Tavernier, Paul Leroux

Abstract:

This article presents the design of a four-channel front-end application specific integrated circuit (ASIC), ATLAS liquid argon front-end (ALFE), developed for the readout of the liquid-argon calorimeter (LAr) detector in the ATLAS experiment at the Large Hadron Collider (LHC). ALFE enables the readout of current signals induced in the LAr …
