A Summating, Exponentially-Decaying CMOS Synapse for Spiking
... We have proposed a new synapse model and a specific CMOS implementation of the model. In our theoretical analysis, we have ignored all parasitic effects which can play an significant role in the circuit behavior. For example, as the source follower M3 − M4 provides the gate voltage of M2 , switching ...
