| Abstract: | In the quality control of LCD/LCM, the measure to micro-current is the important factors to the result of detection. Detection circuit converted from micro-current signal to voltage signal is designed in the measurement of micro-current, including the function of amplifying and filtering .A design project is proposed to control automatically current range with analog switch and adjust cut-off frequency of current with clock pulse inputed . Simulation shows the result is better. |
