英文摘要：

A feature of existing BIST of analog integrated circuit is hardware excess. To solve this problem a new approach of embedded test in amplitude--frequency characteristics based on pulse testing technology is proposed for the first time in this paper. The optimization selection strategy of test parameters is given and proved in theoretical. The proposed scheme provides self--testing with the processor internal resources. Therefore, the hardware cost is reduced in higher degree and the test reliability is improved at the same time. Furthermore, fre- quency domain analysis eliminates the limitations that the input/output signals must be synchronized. Experimental results demonstrate the diagnosis is fast and accurate rate up to 90%.
