发明名称 System and method for analog voltage processing in wide range for cold-cathode fluorescent lamp
摘要 System and method for processing analog voltage for cold-cathode fluorescent lamp. The system includes a voltage-to-current converter configured to receive an input analog voltage signal and generate a first current signal, and a current processing component configured to receive the first current signal and a predetermined current and generate a second current signal. Additionally, the system includes a current-to-voltage converter configured to receive the second current signal and generate an output analog voltage signal, and a dimming controller configured to receive the output analog voltage signal and generate a control signal for driving at least a cold-cathode fluorescent lamp. The voltage-to-current converter, the current processing component, and the current-to-voltage converter are configured to be biased between a first power supply voltage level and a second power supply voltage level.
