One of the major problems associated with integrated DC-DC converters used in state of the art Power Management ICs (PMICs) is dynamic performance and stability degradation due to off-chip component and output current variations. A high accuracy built-in self-test (BIST) architecture measuring load inductance and DC resistance (DCR) of DC-DC converters is presented. The DCR measurement of the inductor...
Lossless load current sensing ability is one of the most desirable features of contemporary current-or voltage-mode-controlled DC-DC converters. Current sensing can be used for short circuit detection, multi-stage converter load balancing, thermal control, and load-independent control of DC-DC converters (Woo et al., 2008). Recently, current sensing techniques using the existing inductor series DC...
