A Noise-Efficient Neural Recording Amplifier Using Discrete-Time Parametric Amplification
This letter proposes an instrumentation amplifier for neural recording applications whose measured noise efficiency factor (NEF) is 2.2. A discrete-time parametric amplifier is adopted as a preamplification stage to lower the input-referred noise, thus imp ...
IEEE2018An integrator-differentiator TIA using a multi-element pseudo-resistor in its DC servo loop for enhanced noise performance
In this paper, we present an integrator-differentiator transimpedance amplifier (TIA) featuring a multielement pseudo-resistor (MEPR) in the DC feedback path for improved noise performance in the presence of non-zero DC input currents. The presented protot ...
