MOSFET Replaces Switch #1: 01/20/94 EDN-Design
Ideas / 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:
10/03/2002 EDN - Design Ideas / 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.. |

MOSFETs reduce crosstalk effects on analog switches:
05/29/03 EDN-Design Ideas / 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.... |
Simple Circuit Detects Current Pulses: 01/06/94
EDN-Design Ideas / The pulse detector provides a
visible indication of positive and negative current
pulses. The pulses amplitudes can vary from20 to150
mA. The pulses durations can range from10 to40 msec,
and their repetition rate can span40 to180
pulses/minute.

Simple Isolated Supply Design Suits FixedDCVoltage
Systems : 12/23/02 Electronic Design - Ideas for
Design / Most high-voltage systems that include
low-voltage ICs must inject isolated supplies into
their setups. The design and implementation of these
supplies is usually quite involved. However, a
simple approach is possible for systems in which
