The analog of a synapse in VLSI is that of a multiplier, the Gilbert multiplier
Pulse based neural network synapses
In a pulse based network, the weighted contribution of a synapse can be implemented using a single transistor.
- Pfet for excitatory synapse
- Nfet for inhibitory synapse
- The weight can be set by changing $Wi$ the biais voltage or $\Delta t$.
