OTA based 200 G {\Omega} resistance on 700 {\mu} m2 in 180 nm CMOS for neuromorphic applications
C Mayr, M Schultz, M Noack, S Henker… - arXiv preprint arXiv …, 2014 - arxiv.org
Generating an exponential decay function with a time constant on the order of hundreds of
milliseconds is a mainstay for neuromorphic circuits. Usually, either subthreshold circuits or
RC-decays based on transconductance amplifiers are used. In the latter case,
transconductances in the 10 pS range are needed. However, state-of-the-art low-
transconductance amplifiers still require too much circuit area to be applicable in
neuromorphic circuits where> 100 of these time constant circuits may be required on a …
