Test trade-offs for different dynamic testing techniques for analog and mixed-signal circuits

Abstract

Several methods for testing the dynamic characteristics and the frequency response of analeg and mixedsignal circuits include input excitations consisting of single or multiple sine waves, pulses, pseudo/white noise or normal operating signals. These techniques differ widely in the test measurement time and the data processing time required for the frequency response characterization, as well as in their effectiveness for detecting errors. This paper will provide a comparative study of the different dynamic testing techniques in terms of the measurement and analysis times as well as test effectiveness.
