This paper presents the design of system in package for a low-power active electrode module. The main aim of this research is to provide a low-cost, high-density, and high-quality module, exploiting the features of a System-in-Package (SiP) solution. To the best knowledge of the authors, this is the first time that SiP technology has been used in the development of a modular active electrode. Two...
One of the major challenge in neural prosthetic device design is to ensure charge-balanced stimulation. This paper presents a new calibration technique to minimize the mismatch between anodic and cathodic current amplitudes. The proposed circuit mainly consists of a digital and an analog calibration, where a successive approximation register (SAR) logic and a comparator are used in digital calibration...
An application specific integrated circuit (ASIC) for body sensor network (BSN) was presented in this paper. Dedicated for low power wireless BSN-on-chip, the ASIC consists of reconfigurable analogue front-end (AFE) block, a 12-bit analogue-to-digital converter (ADC), a low power 32-bit RISC CPU ARM7TDMI, a scalable Fast Fourier Transform (FFT), a wireless power management unit (PMU) with battery...
