In recent years, neural network accelerators have been shown to achieve both high energy efficiency and high performance for a broad application scope within the important category of recognition and mining applications. Still, both the energy efficiency and performance of such accelerators remain limited by memory accesses. In this paper, we focus on image applications, arguably the most important...
We present a low-cost, portable electrochemical analysis system using impedimetric measurements rather than more commonly used potentiometric techniques. The presented impedance spectroscopy (impedimetric) technique uses a small perturbation to obtain a linearized response without affecting the composition of the sample as opposed to cyclic voltammetry (potentiometric) which repeatedly reduces and...
We describe an integrated CMOS electrochemical sensor with on-chip electrodes and packaging. The CMOS chip was fabricated in a standard 0.5 µm CMOS process, and it contains potentiostat circuits with integrated array of three electrode cells. In the potentiostat circuit, we designed high performance folded cascode class-AB operational amplifiers with rail to rail input and output suitable for low...
