Toward Mem-Re-Sensors: Memristor-Like Pinched Hysteresis in an Open-Loop MEMS Resonator Using Third-Order Duffing Nonlinearity

Abstract

For the first time, it is shown that a pinched hysteresis response can be observed in a MEMS resonator when subject to parametric modulation and Duffing nonlinearity. The resultant memristor-like device operates in an open-loop configuration, without the need for a phase-locked loop based feedback control mechanism, to generate discontinuities in response to a stiffness perturbation. This simplifies the peripheral electronics needed to realize memristor-like operation using MEMS resonators, which is a key to realizing practical devices based on this approach. As alternatives to classical computing architectures begin to emerge, we see this work as providing a foundation towards integrated sense, memory, and compute functionality within a single device, which is essential for emerging computing paradigms such as neuromorphic and in-sensor computing.[2026-0062]
