| Abstract: | To solve the problem of modulating and driving MEMS infrared source, a driving system with FPGA and voltage regulator integrated circuit ADP3336 was proposed. The control method with direct tunable square wave is adopted by studying the radiant spectrum and the driving characteristics of the device. FPGA is used to modulate the frequency and duty cycle of the digital pulse. Voltage regulator ADP3336 is used to drive the sources with voltage deviation less than 0.1 V and the driving efficiency achieves 80.1%. This driving circuit can meet the requirements of driving MEMS infrared source with high power, high accuracy, high driving efficiency and deep modulating. It provides the technical foundation to the application of the new type of infrared source device. |
