摘　　要：基于个人集成电路专用模拟程序(PSPICE),设计了六忆阻桥突触电路。通过三角脉冲电压刺激信号,对忆阻桥突触的眨眼反射特性进行了仿真与分析,实现了眨眼反射的短暂习惯化、长期习惯化、恢复习惯化等特性。仿真结果表明,六忆阻桥突触电路能够模拟实现眨眼反射的习惯化,具有快速学习、记忆和抗遗忘等特点,可以模拟生物学习、记忆和对环境的适应性。基于人工突触电路的眨眼反射习惯化的探索对于将生物学习引入神经态系统具有一定的现实意义。Based on personal simulation program with integrated circuit emphasis(PSPICE),a six memristor bridge synaptic circuit was designed.The system simulation and characteristic analysis of blink reflex was then carried out by simulating the stimulus signal with triangular pulse.The short-term habituation,long-term habituation and recovery habituation of blink reflex were finally realized.The simulation results show that the six memristor bridge synaptic circuit,which can simulate the realization of blink reflex habituation and has the characteristics of fast learning,memory and anti-forgetting,can simulate biological learning,memory and environmental adaptability.The exploration of the habituation of blink reflex based on artificial synaptic circuit has a certain practical significance for introducing biological learning into the neuromorphic system.
