This paper presents a configurable analog front-end (AFE) for low-power neural recording systems that is capable of the current-to-voltage converter, programmable gain, ultra-high input impedance, low-noise, and wide bandwidth. A 6-channel AFE consisting 6 1-channel AFEs also introduced in this paper. The proposed designed on 180nm CMOS process low noise operates over frequency range 0.5 Hz to ...

 Abstract—The dual-band recording of the local-field potential (LFP, 0.1Hz~200Hz) and the spike potential (SP, 200Hz~10kHz) is important for physiological studies at the cellular level. Recent study shows that the LFP signal plays important roles in modulating many profound cellular mechanisms. Although various bio-signal acquisition circuits have been reported over the years, few designs are ...

Abstract This research work designs a prototype of an active-loaded differential amplifier using Double-Gate (DG) MOSFETs. The following text outlines the design with testing in developing conceptual understanding and its requirement. designed model uses mathematical models while assessing possible limitations DG MOSFET. exhibits gain 4 V/V, bandwidth 1 MHz. common-mode output values were teste...

The absence of cardiovascular disease (CVD) diagnostic and management solutions cause significant morbidity among populations in rural areas the coronavirus 2019 (COVID-19) emergency. To tackle this problem, paper, development an Internet things (IoT) assisted ambulatory electrocardiogram (ECG) monitoring system is presented. system’s wearable single-channel data acquisition device supports 25 ...

Abstract This paper presents a comparative EMI susceptibility study of different integrated operational transconductance amplifier (OTA) topologies. We analyzed conventional well-known topologies based on the Miller OTA and folded cascode concepts with lower power consumption. The output dc voltage shifts induced by supply input common mode high frequency disturbances are presented. On top comp...

In this work, we focus on the Power Supply Rejection and Common Mode performance of inverter based ring oscillators intended for use in VCO ADCs. We show that they are closely related to circuit’s mismatch behavior which perform a systematic analysis. To end, construct theoretical model these oscillators, Pelgrom’s model. addition, generalize include generic tuning circuit. broad analysis, that...
