Neuromorphic Circuits and Systems: From Neuron Models to Integrate-and-Fire Arrays

In the field of neuromorphic engineering, we seek to design systems with direct correlates to the structure and functionality of the human brain. The brain is capable of performing complex tasks in real time under low-power, lightweight, and small-size constraints. Therefore, by designing systems inspired by biology, we further bridge the gap between the specifications of engineered systems and that of the brain. Research in the neuromorphic field spans designing neuron models, implementing these models in VLSI technology, designing neuromorphic chips consisting of arrays of neurons, developing spiking neural network algorithms, and developing neuromorphic sensors. In this chapter, these ideas along with the future of the field will be discussed.
