A Direct Digitizing, 1MHz Bandwidth, 28fA/√Hz Current Sensing Front-End Based on a Mixed-Signal Integrator-Differentiator TIA in 28nm CMOS
Low-noise and high-throughput current sensing front-ends are required for sensor systems such as electrical impedance spec-troscopy, ion conductance microscopy, or nanopore-based DNA sequencing [1]–[3]. Such applications require fA/√Hz noise floor and at the same time hundreds of kHz or even MHz bandwidth (BW).
