Abstract: This paper presents a novel amplifier architecture intended for low power neural recording applications. By using continuous-time signal representation, the proposed topology predominantly leverages digital topologies taking advantage of efficient techniques used in time domain systems. This includes higher order feedback dynamics that allow direct analogue signal quantization and near ideal integrator structures for noise shaping. The system implemented in 0.18 μ m standard CMOS demonstrates the capability for low noise instrumentation with a bandwidth of 6 kHz and highly linear full dynamic range. Simulation results indicate 1.145 μW budget from 0.5 V supply voltage with an input referred thermal noise of 7.7 μVrms.
