Integrate and Fire (I&F) as an ADC
Biphasic Integrate and Fire (I&F) circuit
Project Description (What)
We propose to use a biologically inspired circuit called as Integrate and Fire as an Analog-to-digital (ADC) replacement. I&F circuit is asynchronous, meaning it has no clocks, as compared to the conventional ADCs. The asynchronous property leads to a significantly lower output data rate and lower power consumption as against conventional ADCs. I&F trades off bandwidth and power for a more complex recovery mechanism. We have successfully used the I&F as a data encoder in neural recording applications and now trying to use it as a sampler for massive sensor networks.
Collaborators (With Whom)
- Alexander Singh Alvarado - Working on various signal processing techniques for reconstructing the original signals from the asynchronous samples.
- Jie Xu (Jessie) - Worked on the front-end electronics, low-noise amplifiers and V-I (Gm) for neural signals.
