Description
This lecture covers electrode offsets, common-mode interference, and noise rejection techniques in bioamplifier circuit architectures. It discusses continuous-time and clock-based techniques, capacitive feedback networks, Miller integrator feedback networks, and capacitive amplifier feedback networks. The presentation also delves into integrated high-value resistors, programmable resistance values, and linearity improvement techniques. Furthermore, it explores fully differential neural amplifiers, optimal OTA topologies, and tunable-bandwidth bioamplifier realizations. The lecture concludes with practical realizations, noise characteristics of symmetrical OTAs, and design considerations for low-noise LNAs.
