an indirect current sensing technique for iddq and iddt tests
An indirect current sensing technique for I DDQ and I DDT tests is proposed in this paper. This is accomplished by utilizing the pervasive on-chip voltage regulators and thus have little or no impact on CUT's design and its performance. We demonstrate that the proposed technique can be applied to both I DDQ and I DDT tests. Experiments were successfully conducted in SPICE simulations assuming the TSMC 0.18?m CMOS technology.
