为了克服继电器在集成电路测试板上触点烧蚀故障率较高,断开时易产生电磁干扰和开关时间过长等缺点,提出了一种基于MOS管的新型转换开关电路,能更加有效地测试芯片,显著降低芯片的成本。本文详细讨论了集成电路测试的要素和基本原则,继电器在测试板上的应用及其局限性,基于MOS管的新型转换开关电路的特点及控制原理。仿真结果表明,该电路在10v电源电压下开关的转换速度为70μs,工作频率可达100kHz以上,灵敏度高,适用于集成电路测试。

In order to overcome the disadvantages of contacts ablation, electromagnetic interference and longconduction time when relay is used in load board of integrated circuits, we propose a new control circuit based on MOS switch , this circuit is more effective in chip testing and can reduce the cost significantly. This paper detailedly discusses the elements and basic principles of integrated circuit testing, the application and limitationsof the relay when it is used in the load board, and the new features and control theory of this new control Simulation results show that switch conversion rate of the circuit in the 10 V power supply voltage is 70 the circuit has high sensitivity,over the operating frequency of up to 100 kHz, i...
