MOSFET enhances Voltage Regulator's overCurrent protection: 03/03/05 EDN
Design Ideas / (added 2/06) The classic LM317 adjustable-output linear
voltage regulator offers a relatively high, if package-dependent, current-handling
capability. In addition, the LM317 features current limiting and thermal-overload
protection. With the addition of a few components, you can enhance an LM317-based
voltage regulator by adding a high-speed short-circuit current limiter (Figure 1). |

MOSFET Replaces Switch #1: 01/20/94 EDN-Design Ideas / (Electronic Circuit
diagram added 03/03) By using a cheap, readily available MOSFET, you can use a
single-pole switch to turn a bipolar power supply on and off without consuming extra
power. In Fig1, the switch simply controls the MOSFET gate, which switches on the
negative supply. Resistor R, which can be several megohms, is not necessary if the ±6V
rails are permanently connected to a load, such as an op-amp circuit. Because the
MOSFETs RDS (ON) is a fraction of an ohm, power loss is minimal, and the circuit suits
moderate-consumption, battery-operated circuitry |

MOSFET Serves as Ultrafast plate Driver: 10/03/02 EDN Design Ideas /
(added 1/05) The circuit in Figure 1 provides a 20-MHz square wave across a set
of highly capacitive ion-deflection plates in an experimental instrument. To get the
required deflection, the plate voltage must be 20 to 30V, much higher voltage than
conventional logic or driver families can provide. To minimize artifacts, the rise and
fall times must be very fast, with a minimum of overshoot and ringing.... |

MOSFET Tutorial:
Power MOSFETs are well known for superior switching speed, and they require very
little gate drive power because of the insulated gate. In these respects, power
MOSFETs approach the characteristics of an “ideal switch”. Application Note

MOSFETs reduce crosstalk effects on analog Switches: 05/29/03 EDN Design
Ideas / (added 1/05) Some cost-effective analog
multiplexer/demultiplexer ICs, such as the CD4053 and CD4066, find frequent use as
signal distributors. These digitally controlled analog switches have low
on-resistance. However, with all channels in the same package, crosstalk can be
annoying and unavoidable. Figure 1 provides a cost-effective and viable method of
solving this problem.... |

MOSFETshunt regulator substitutes for series regulator: 11/25/04
EDN-Design Ideas / (added 5/05) You would normally use a series linear regulator
or a dc/dc converter to obtain 3V dc from a higher supply. However, when breadboarding
a concept, you may be able to use a shunt regulator, especially if a series regulator
of the correct voltage is unavailable. The MOSFET in Figure 1 can replace a zener
diode in a shunt regulator and provide lower output impedance than a zener diode.... |
