摘　　要：针对无线胶囊式内窥镜系统低功耗、微型化,以及其发射范围等要求,对原有的发射电路进行优化和改进,以降低电路总电流,从而降低发射电路的总体功耗。电路板采用双面设计,电路元器件均采用表面贴装器件(SMD)贴片形式,利用DXP2004软件设计和制作PCB电路,印刷电路板尺寸减小为Ф10mm,使胶囊顺畅地经过肠胃系统。Carries out optimization and improvement to the original transmission circuit, in view of requesting low power consuming and microminiaturization in wireless capsule endoscope system. The improving of original electric circuit is according to the demanded transmitting distance of wireless endoscope system. Reduce joint current of the electric circuit to cut overall power consuming of the transmission circuit. The circuit board is designed to two-sided style using protel DXP2004, and the primary devices are chosen Surface Mounted Devices （SMD）. Finally,the diameter of circuit board is only 10mm,which is small enough to make capsule endoscopy pass through the stomach system smoothly.
