# Analog Spiking Neuron Circuit - Caravel Submission
This is the Google/EFabless/Skywater Caravel submission of an [Analog Spiking Neuron Circuit.](https://ieeexplore.ieee.org/document/9184447) The submission also includes a SONOS transistor array.

## Neuron circuit
The circuit in the original paper is in 130nm technology and has a vdd of 300mV. Skywater pdk is hybrid 180nm/130nm node where the minimum transistor length is 150nm.
As a result vdd needs to be higher in order to get the circuit to work properly. In simulation 700mV seems to work well.
