This paper presents a low-cost analog test system with diagnosis capabilities. The tester is able to detect faults in any linear circuit by learning a reference circuit behavior in a first step, and comparing this behavior against the output of the circuit under test in a second step. For a faulty circuit, a third step takes place to locate the fault. The(More)
A low cost method for testing analog RF signal paths suitable for BIST implementation in a SoC environment is described. The method is based on the use of a simple and low-cost one-bit digitizer that enables the reuse of processor and memory resources available in the SoC, while incurring little analog area overhead. The proposed method also allows a(More)
