IC Maintains Uniform Bias for GaAs Mesfets - 08/22/02 EDN-Design Ideas: The
gate-turn-on threshold voltage for GaAs MESFETs (gallium-arsenide metal-semiconductor
field-effect transistors)varies considerably from part to part, even within a given
lot. That behavior makes biasing difficult, especially if you want to design the
device into a high-volume product. To overcome this drawback, you can introduce
a.....(design idea added 1/05) |

Improve FET Based Gain Control - 12/06/01 EDN-Design Ideas: One problemwith
standard FET gain-control circuits is increased noise when you use the FET as a part
of a resistive attenuator in series with an op amp. This configuration attenuates the
signal before amplification; hence, it requires much higher gain bandwidth and better
noise performance from the op amp.....(design idea added 1/05) |

Improved Power MOSFETS Boost Efficiency IN A 3.5kw Single Phase PFC - This paper
charts the technological evolution of APT’s powerMOSFETs from the earliest PowerMOS IV
designs to the latest PowerMOS 7TM products. The improvement in performance of a 3.5kW
boost converter equipped in turn with different generation products is evaluated, as
well as the ....( app note added 4/08) |

Isolated MOSFET Driver has Wide Duty Cycle Range - 04/29/04 EDN-Design Ideas: The
main application for the circuit in Figure 1 is for driving power MOSFETs with signals
ranging in frequency from 1 Hz to 300 kHz and with duty cycles from 0 to 100%. You
achieve this goal by using a coreless pc-board transformer. The switching frequency in
most power-electronics circuits ranges from a few hertz to a few hundred
kilohertz.....(design idea added 1/05) |
