D/A Converter ASIC uses Stochastic Logic - 10/24/96
EDN-Design Ideas To effect A/D and D/A conversion using ASICs,
you usually need mixed-signal analog and digital processing.
Mixed-signal silicon is more expensive than purely digital circuitry
to process and test. In the case of FPGAs,.... [Design Idea by J

DAC and op amp provide variable-control voltage - 6-Dec-01 Issue of EDN
Early DACs contained standard R-2R ladder networks, and produced a negative output
voltage. These early DACs, such as the MAX7837/7847 and the MAX523, require both
positive and negative supply rails to accommodate their negative output. With the
transition to single-supply ICs, however, many modern DACs operate with a single
supply rail and an inverted R-2R ladder network.... [Design Idea by Chad Olson, Maxim

DDS IC plus frequency-to-voltage converter make low-cost DAC - 5-Feb-04
Issue of EDN Precision DACs are essential in many consumer, industrial, and
military applications, but high-resolution DACs can be costly. Frequency-to-voltage
converters have good nonlinearity specifications—typically, 0.002% for the AD650—and
are inherently monotonic. This Design Idea shows how you can use a
frequency-to-voltage converter and a DDS (direct-digital-synthesizer] chip for
precise.... [Design Idea by Noel McNamara, Analog Devices, Limerick, Ireland] |

Designing high-current chokes is easy - 24-Jun-04 Issue of EDN
Somewhat unusually, this Design Idea deals with a formula rather than a circuit. You
might think that all the basic formulas of magnetic phenomena were discoveredthan a
century ago. In fact, they probably were, but, at the time, some were of little
practical interest and were essentially disregarded and never included in books or
formula tables.... [Design Idea by Louis Vlemincq, Belgacom, Evere, Belgium] |

Designing High-Current Vrm Compliant CPU Power Supplies - 10/26/00
EDN-Design Ideas Modern high-speed microprocessors require fast delivery of
enormous supply currents in microsecond time frames, tight supply-voltage tolerance,
and intelligent voltage programming. The latest CPU voltage-regulator specifications
from Intel and AMD call for load-current slew rates of 50 to 200A/µsec and peak
currents of 60 to more than 120A. These demands are transforming the design of
portable power supplies to levels almost like those of utility power. The core supply
voltage of the CPU must remain within its specified tolerance even when the processor
performs a current-load step from nearly 0 to more than 60A in a few microseconds.
This process requires a proper design approach and knowledge of advanced
power....[Design Idea added 5/05] EDN is migrating links. This link is not verified.

Double DAC rate by using mixers as switches - 5-Feb-04 Issue of EDN
You can effectively double the sample rate of a DAC by interleaving two DACs into a
single unit. Updating each DAC on an alternating basis and switching to the
appropriate output double the effective throughput of the overall system. It is
essential to overall performance that you use a high-quality, high-speed switch in the
multiplexing of the DACs' outputs.... [Design Idea by Randall Carver, Analog Devices,

DPPs make nonvolatile microvolt DAC - 31-Oct-02 Issue of EDN The
availability of a seemingly limitless variety of monolithic DAC chips makes it easy to
implement most digital-to-analog-conversion applications with a single off-the-shelf
device. Sometimes, an unusual set of requirements necessitates a multichip approach,
however. One example of such a requirement is the need for nonvolatility of the DAC's
setting in power-up and -down cycles.... [Design Idea by Stephen Woodward, University
of North Carolina, Chapel Hill, NC] |
