0.65 V integrable electronic realisation of integer- and fractional-order Hindmarsh–Rose neuron model using companding technique

摘要: Some neurons like neocortical pyramidal adapt with multiple time-scales, which is consistent fractional-order differentiation. The neuron models are therefore believed to portray the firing rate of more accurately than their integer-order models. It has been studied that as fractional order differentiator and integrator involved in model decreases, bursting frequency increases. opposite effect observed on increasing external excitation. In this study, integer- Hindmarsh–Rose (HR) have implemented using sinh companding technique. Besides, application HR a simple network two also considered. designs offer low-voltage low-power implementation along electronic tunability performance characteristics. Due use only metal-oxide semiconductor (MOS) transistors grounded capacitors, proposed can be integrated chip form. On comparing existing implementations, show better terms power consumption, supply voltage, flexibility. circuits verified 130 nm complementary MOS (CMOS) technology process provided by Austrian Micro Systems HSPICE simulation software.
