Abstract:
A new design for a true-linear generator suitable for electrochemical measures is presented. The main component of generation system is an MAX038 chip, a high-frequency relaxation-type oscillator. The design is completed with a digital interface for computer control and an output stage to make signal suitable for cyclic voltammetry experiments. A digital circuit is also included to obtain single sweep signals by isolating one period or a half-period from continuous original output. Performance of presented generator is tested up to 1 MV s(-1) obtaining good stability and linearity.
