A 'neural' A/D converter utilizing Schmitt trigger
Giuseppe Di Cataldo, G. Palumbo · 2002
Theoretical considerations are presented regarding the stability and the physical realizability of a new A/D converter based on the Hopfield neural network. The equivalent circuit made and described by M.J.S. Smith and C.L. Portmann (1989) is analyzed in order to solve the problem in a different way. The authors adopt the same circuit scheme realized with Schmitt triggers, but modifying their hysteresis and thresholds in an appropriate manner. The role played by the amplifier response time is widely illustrated, and the network theoretical behavior is analyzed. A proof that validates the correct operation of the circuits is reported.>
