A Chopper Stabilized, Current Feedback, Neural Recording Amplifier
IEEE Solid-State Circuits Letters, 2019 Advanced neural prosthetics requires high density neural recording and stimulation electrodes interfacing with the tissue. For an implantable device, area, power consumption, and noise performance are the key design metrics. Due to the low-frequency nature of the recorded signals, chopping technique is inevitable to satisfy the noise requirement while ...

Stability study and dynamical analysis of the multicellular chopper [PDF]
International Journal of Simulation and Process Modelling, 2018 The dynamical properties of a two-cells chopper connected to a particular nonlinear load are described in this paper. Some interesting and complex attractors are obtained. We analyse the system by means of Lyapunov exponents, fractal dimension, Poincaré mapping, first return, bifurcation diagram and phase portraits, respectively. Our model is described
