Some low-dropout regulators (LDOs) use multiple feedback loops to improve output voltage transient response. In many of these cases, some or all of the loops are inside the IC. Accessing these loops ...
Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...
A version of Part 1 appeared in the Dec. 2011/Jan. 2012 issue of Test & Measurement World. See the PDF. In January 1979, Electronic Test published an article claiming that a single test circuit that ...
