Analog multiplexer uses flying capacitors - 22-Jan-04 Issue of EDN This
Design Idea describes a way to increase the number of analog inputs to your
microcontroller for cases in which adding an analog-multiplexer chip or upgrading to a
microcontroller withinputs might be impractical. If the microcontroller you're using
has some spare I/O pins and at least one of them is bidirectional or is amenable to
tristating, you can configure a simple analog multiple....[Design Idea by Dick Cappels,

Analog Multiplexers help Test IS IRQs & DrQs - 12/07/95 EDN-Design Ideas
There are 11 interrupt-request (IRQ) lines and seven DMA-request (DMQ) lines available
on an ISA connector. These lines are IRQ3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15 and
DRQ0, 1, 2, 3, 5, 6, and 7. For diagnostic purposes, you should equip each line with
its own control circuit to set each output low, high, or in tristate mode to avoid
conflicts with installed add-on boards....[Design Idea by Jerzy R Chrzaszcz, Institute

Analog multiplier works over large frequency range - 09/16/99 EDN-Design
Ideas....Schottky-diode double-balanced mixers are common elements in analog and
digital telecommunications circuits that operate at radio and microwave frequencies.
Transistor analog multipliers, such as log-antilog, MOS, and variable-transconductance
types, are usually limited to frequencies of much less than 1 GHz. In the
circuit....[Design Idea by Hubert Houtman, Consultant, Blaine, WA] |

Astable Multivibrator Projects - Astable or free-running multivibrators have
been used in home-built amateur radio equipment for many years. The basic circuit is a
two stage amplifier with AC-coupled feedback from output to input. One transistor
stage is on ( conducting current )....(designed added 08/08/08) |

Fast 10-line-to-one-line
data selector/multiplexer comprises only two ICs - 11-Jun-09 Issue of EDN
When dealing with logic operations over BCD (binary-coded-decimal] numbers, you often
need a 10-line-to-one-line data selector/multiplexer. In the past, you could use the
famous 16-line-to-one-line 74150 multiplexer IC. Nowadays, however, when you look at
the Web sites of the renowned semiconductor houses....[Design Idea by Marián Štofka,

Force/sense connection eliminates
multiplexer on-resistance error - 22-Jan-04 Issue of EDN Digitally
controlled gain is an everyday analog-design element. You frequently find this element
in an op-amp-based, transimpedance current-to-voltage converter. When you design
digital gain control into such a converter, the usual scheme is to arrange things such
that a digital multiplexer selects the appropriate feedback resistor for each gain
figure....[Design Idea by Stephen Woodward, Marine Sciences, Chapel Hill, NC] |
