Abstract

In order to reduce the electrode polarization effect, current excitation mode is widely adopted. The accuracy of exciting current is limited by the character of Voltage Controlled Current Source (“VCCS”). Commonly, VCCS is build by precision components and high speed OPs. However, in the field where high components density and precision is needed, the scheme would expose some inevitable disadvantages. In this paper, a new integrated solution and a platform based on FPGA are propounded.
