会产生一个Spike (比如30mV),并且会将膜电位重置到一个重置电位V_{reset} = -60mV并维持一个给定的不应期时间\tau_{ref} = 2ms(以上给定的参数仅为参考),然后再利用LIF的被动电位公式进行下一步的计算。
Herein, a diffusive CH3NH3PbI3(MAPbI3)-based memristor with superior amplitude-frequency characteristics and highly linear conductivity modulation for more than 1000 states have been fabricated for the construction of a leaky integrate-and-fire (LIF) bio-inspired neuron. The as-designed LIF model ...
Leaky Integrate-and-Fire LIF模型,顾名思义,包含了以下三大特征: Leaky:存在欧姆漏电流。 Integrate:一个能积累电流的部件,电容。 Fire:当输入电流足够大的时候,膜电压会产生突变(spiking) 它的线性微分方程表达式如下: CdVmdt=I−gleak(Vm−Eleak) 由方程易得LIF模型有这样的性质 存在明确的临界电压 Vthr...

We introduce an ultra-compact electronic circuit that realizes the leaky-integrate-and-fire model of artificial neurons. Our circuit has only three active devices, two transistors and a silicon controlled rectifier (SCR). We demonstrate the implementation of biologically realistic features, such as spi...
