While analog computing is attractive for implementing machine learning (ML)
processors, the paradigm requires chip-in-the-loop training for every processor
to alleviate artifacts due to device mismatch and device non-linearity.
Speeding up chip-in-the-loop training requires re-biasing the circuits in a
manner that the analog functions remain invariant across training and
inference. In this paper, we present an analog computational paradigm and
circuits using "shape" functions that remain invariant to transistor biasing
(weak, moderate, and strong inversion) and ambient temperature variation. We …
