By replacing a single feedback capacitor with a clamped T-capacitor network, the proposed amplifier can achieve same mid-band gain with less input capacitance, resulting in a smaller silicon area and higher input impedance. Fabricated in 0.35μm CMOS, the amplifier occupies merely 0.056mm2. It achieves 38.1-dB mid-band gain with 1.6pF input capacitance, and hence has a Cin/Gain ratio of 20fF.V/V. It has an input referred noise of 6.72μVrms over 8.4-kHz bandwidth and NEF of 4, and consumes 6μW. In-vivo recordings from an animal experiment are also demonstrated. © 2012 IEEE.||Source Title:||2012 IEEE Biomedical Circuits and Systems Conference: Intelligent Biomedical Electronics and Systems for Better Life and Better Environment, BioCAS 2012 - Conference Publications||URI:||http://scholarbank.nus.edu.sg/handle/10635/83340||ISBN:||9781467322935||DOI:||10.1109/BioCAS.2012.6418430|
