CMRR Boosted Instrumentation Amplifier for Biomedical Application
This research paper discusses about a design of an amplifier for its use in an Analog Front End for Biomedical signal acquisition. The design of an AFE is also specific to the signal of interest. This paper deals with the design of an Analog Front End using 180nm process. An amplifier is a key component of an AFE. For instrumentation amplifier to satisfy theoretical results the OPAMP used must be close to ideal. The simulations are performed using TANNER EDA tool

An ECG-on-Chip with 535-nW/Channel Integrated Lossless Data Compressor for Wireless Sensors
This paper presents a low-power ECG recording system-on-chip (SoC) with
on-chip low-complexity lossless ECG compression for data reduction in
wireless/ambulatory ECG sensor devices. The chip uses a linear slope predictor
for data compression, and incorporates a novel low-complexity dynamic
coding-packaging scheme to frame the prediction error into fixed-length 16-bit
format. The proposed technique achieves an average compression ratio of 2.25x
on MIT/BIH ECG database. Implemented in a standard 0.35 um process, the
compressor uses 0.565K gates/channel occupying 0.4 mm2 for four channels, and
consumes 535 nW/channel at 2.4 V for ECG sampled at 512 Hz. Small size and
ultra-low power consumption makes the proposed technique suitable for wearable
ECG sensor applications
Low-Power Wearable ECG Monitoring System for Multiple-Patient Remote Monitoring
Many devices and solutions for remote electrocardiogram (ECG) monitoring have been proposed in the literature. These solutions typically have a large marginal cost per added sensor and are not seamlessly integrated with other smart home solutions. Here, we propose an ECG remote monitoring system that is dedicated to non-technical users in need of long-term health monitoring in residential environments and is integrated in a broader Internet-of-Things (IoT) infrastructure. Our prototype consists of a complete vertical solution with a series of advantages with respect to the state of the art, considering both the prototypes with integrated front end and prototypes realized with off-the-shelf components: 1) ECG prototype sensors with record-low energy per effective number of quantized levels; 2) an architecture providing low marginal cost per added sensor/user; and 3) the possibility of seamless integration with other smart home systems through a single IoT infrastructure
