Abstract

This paper describes an eleven channel artificial nerve signal generator with a programmable inter-channel time delay using only a Field Programmable Gate Array (FPGA) and a small number of passive external components. The FPGA is used to create a novel, linearised Pulse Width Modulation scheme which would not be possible with other alternatives technologies such as a micro controller. This signal generator can be used in the testing of multi-electrode cuff system tests without needing to resort to the use of a real nerve. Techniques are developed to improve precision of the signal waveform without increasing cost or hardware complexity. The system described has applicability in other areas where multiple, time skewed, low voltage signals are required. The waveform signal shape and time delay can be modified easily to match the new application.
