Predicting LDMOS DC, Small and Large Signal Behavior

Posted on 01 August 2007

    A new Verilog model for design Thanks to their cost effectiveness and high performance, LDMOS devices are widely used in radio-frequency applications, ranging from digital communication infrastructure (cellular base stations) to low-cost portable radios (private mobile radios), commonly known as Walkie-Talkies. By Amedeo Michelin Salomon and Giuseppe Privitera, STMicroelectronics   To reduce the [...]

The Forward Converter

Posted on 01 August 2007

       Basic construction and function As an aid for understanding, the individual switching states in the steady state system are examined. By Dr. Thomas Brander, Würth Elektronik   Figure 1 shows the basic construction of a forward converter. Whereas the energy is temporarily stored with the flyback converter before it is transferred to [...]

Comparing Regulated Charge-Pump and Inductor-Based DC/DC Converters

Posted on 01 August 2007

       It is the design engineer to make the choice of topology Charge pumps, also known as inductorless DC/DC converters, are a special class of switching DC/DC converter that uses capacitors as energy storage elements. When compared to inductive switching DC/DC converters, which use inductors as energy storage elements, charge pumps offer unique [...]
