Résumé:
A potentiostat is an electronic instrument that plays a critical role in electroplating by
regulating the potential applied to the substrate and providing accurate measurements
of the electrochemical parameters involved. In this project, our purpose is to study and
design the basic fundamental circuit of potentiostat instrument. The different part of
the complete potentiotat instrument began with the potentiostat measuring circuit of
the current passing through the system. A second important designed circuit have to
monitor and control of the electroplating process. Additionally in our electronic analysis
and design we have taken account of the potentiostat's ability to measure and monitor
electrochemical parameters aids in the analysis and optimization of the electroplating
process. Above this, we have modelized electrochemical cell using a lumped model
for several position in the I-V curve to complete the loop of our analysis. The simulator
design tool used in our simulation is PCB Design and Circuit Simulator Software –
Proteus .
