Supply Current Sensor Structure for Testing Σ-Δ Modulators
A novel built-in supply current sensor structure for testing the Σ-Δ modulators is presented in this paper. The dynamic supply currents in modulators unit are captured via scanning in testing mode and analyzed to detect defects. The testing structure has only one current sensor and can readily be expanded for using in other mixed-signal circuits. Simulation results show that the good performances of the testing solution.
