A High TCMRR, Inherently Charge Balanced Bidirectional Front-End for Multichannel Closed-Loop Neuromodulation
(Institute of Electrical and Electronics Engineers, 2019)
This paper describes a multichannel bidirectional front-end for implantable closed-loop neuromodulation. Stimulation artefacts are reduced by way of a 4-channel H-bridge current source sharing stimulator front-end that ...

A Sub-μVRms Chopper Front-End for ECoG Recording
(Institute of Electrical and Electronics Engineers, 2019)
This paper presents a low-noise, low-power fully differential chopper-modulated front-end circuit intended for ECoG signal recording. Among other features, it uses a subthreshold source-follower biquad in the forward path ...

A chaotic switched-capacitor circuit for characteristic CMOS noise distributions generation
(Institute of Electrical and Electronics Engineers, 2017)
A switched-capacitor circuit is proposed for the generation of noise resembling the typical noise spectral density of MOS devices. The circuit is based on the combination of two chaotic maps, one generating 1/f noise ...
