In this paper, a fast transient testing methodology for predicting the performance parameters of analog circuits is presented. A transient test signal is applied to the circuit under (cut) test and the transient response of the circuit is sampled and analyzed to predict the circuit’s performance parameters. An algorithm for generating the optimum transient(More)
We propose a new Simulation-After-Test (SAT) methodology for accurate diagnosis of circuit parameters in large analog circuits. Our methodology is based on constructing a non-linear regression model using prior circuit simulation, which relates a set of measurements to the circuit's internal parameters. First, we give algorithms to select measurements that(More)
Production test costs for today's RF circuits arerapidly escalating. Two factors are responsible for thiscost escalation: (a) the high cost of RF ATEs and(b) long test times required by elaborate performancetests. In this paper, we propose a framework for low-cost signature test of RF circuits using modulation ofa baseband test signal and subsequent(More)
In this paper; we discuss the capabilities of the MiST PROFIT (Mixed Signal Test Program for Fault Inst’rtion and Testing) software fo r hierarchical fault modeling, tolerance modeling, fault cluste,ring and fault diagno.i.is of complex mixed-signal sysrems. The sofrware is designed to exploit the relationships between high level system spec@cations and(More)
With the increasing complexity of manufacturing processes and the shrinking of device geometries, the performance metrics of integrated circuits (ICs) are becoming increasingly sensitive to random fluctuations in the manufacturing process. We propose a diagnosis methodology that can be used to infer the cause(s) of variations in performance of analog ICs.(More)
In this paper, a novel algorithm has been proposed to measure system specifications of an integrated transmitter, which capture the non-linearities of the system-under-test. The measurement of these specifications is important, as these determine the amount of “interference” created by the transmitting system in adjacent channels while transmitting data in(More)
