This work presents a hardware Liquid State Machine (LSM) optimized for speech classification using a high-linearity body-driven VCO-based IF neuron. The proposed neuron operates under 0.8V, leveraging phase-domain integration. Integration linearity is further enhanced through body-driven VCO and a differential structure. Additionally, a novel voltage-mode synapse architecture based on ring VCO structure is introduced. The LSM consists of 36 reservoir neurons and 238 synapses, targeting 88.0% classification accuracy for spoken digit recognition. The recurrent neurons will be fabricated in Samsun 28nm CMOS process. |
