چکیده

A Built-In Self-Test (BIST) approach is described which is designed to test the analog portion of mixed-signal integrated circuits and systems. The BIST circuitry is located in the digital portion of the mixed-signal circuitry to minimize area overhead and effects on the analog portion of the mixed-signal system. The approach was evaluated using benchmark circuits for analog testing and found to consistently provide fault coverage greater than 95%, even when acceptable component parameter variations are added to the set of benchmark

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

A Step Response Based Mixed-Signal BIST Approach for Continuous-time Linear Circuits

A new Mixed-Signal Built-in self-test approach that is based upon the step response of a reconfigurable (or multifunction) analog block is presented in this paper. The technique requires the overlapping step response of the Circuit Under Test (CUT) for two circuit configurations. Each configuration can be realized by changing the topology of the CUTor by sampling two CUTnodes with dsffering ste...
