摘要
In the design of ampere detector, the micro-current signal in the electrochemical cell is extremely weak after electrifying, so it is difficult to be distinguished from the noise. A new micro-ampere detector, which uses the data amplifier to enlarge the weak signal, is developed according to the principles of the ampere detection and the potentiostat. The circuit performance of the micro-ampere detector is very stable. The test result is consistent with the theory value. The circuit testing micro-current not only can be applied to the micro-ampere detector, but also can be applied to the other situations with different sensors to test micro-current signals.
