Background:

Front-end electronics in spike sorting systems are critical for detection and sorting accuracy, influencing power and silicon area.
Design parameters of these electronics significantly affect overall system performance.

Purpose of the Study:

To develop a behavioral model for assessing the impact of front-end electronic design parameters on spike processing.
To validate the model using hardware and literature data.
To inform the design of efficient Analogue Front-End (AFE) systems for spike sorting.

Main Methods:

A behavioral model was created to simulate the effects of design parameters like SNR, filter type/order, bandwidth, and converter resolution/rate.
The model was validated by comparing simulated responses to hardware measurements.
Established spike detection and sorting algorithms were tested using data from various literature-reported systems.

Main Results:

The behavioral model accurately predicted circuit responses.
Despite wide variations in design parameters and complexity across different AFE systems, the impact on spike processing performance was found to be relatively small (10-15%).

Conclusions:

The developed behavioral model effectively evaluates AFE design impacts on spike sorting.
Future AFE designs can prioritize efficiency without significantly compromising spike processing performance.
