Abstract: This brief presents a nested ring amplifier with dynamic-cascode-bias and gain-boosting techniques. The proposed amplifier achieves a gain of 90 dB while preserving the high-slew capability.
Abstract: A low power high efficiency neural signal recording amplifier with a novel multi-chopper technique is proposed and implemented in 180nm CMOS. The input referred rms noise is 1.54µV (1–500Hz) ...
