Small-signal analysis of switching dc-dc converters determines their specific transfer functions, for example, for stability analysis or design of a proper input filter. Transfer functions of interest ...

The study protocols were approved by the Institutional Review Board at Taipei Veterans General Hospital, Taiwan, and adhered to the principles of the Declaration of Helsinki. Written informed consents ...

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 ...

Modern video displays provide improved performance compared to, now obsolete, cathode ray tube (CRT) displays. In particular they are now starting to provide brighter images and deeper blacks. In ...

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...
