Improving design and fault detection in linear and nonlinear high frequency circuits by performing a sensitivity based analysis
The rapid growth of wireless communication has led to an increasing demand for reliable and high performance RF products. One way of achieving high reliability and performances is having an efficient test procedure. Considering the complexity of analog testing and the high frequency constraints, testing RF circuits introduces a new challenge to the test community. In this paper, a test method for RF circuits is presented. This test method divides RF circuits between linear and nonlinear circuits. It helps perform a quick and efficient test with a limited number of test vectors. By using this method the design engineer can determine parameters influencing the circuit performances and the best topology that can be used to improve these performances. On the other hand, it helps a test engineer to plan his test strategy and to predict which elements can be isolated by a given test set.
