- Description: Implement a LIF neuron in 130 nm CMOS

- Clock: 10000000 Hz
How it works
Start by applying an input current injection to the LIF neuron.
This gets added to a membrane potential which decays by a factor beta over time.
When the membrane potential exceeds the threshold, a spike is triggered.
How to test
Reset the circuit to set the membrane potential to 0.
The inputs can be changed to vary the current. A higher current will result in a higher spike rate.
