Into The Niche: Fabless Firm Unveils Trio Of Exclusive Products
Fabless companies have a great opportunity to develop truly unique niche products. Wolfson Microelectronics is taking that opportunity. Most new digital still cameras can record short full-motion segments with sound. The DSP core in...
Simultaneously Sampling 14-Bit ADCs Double Channel Count, Halve Footprint
Sampling eight 14-bit channels simultaneously at 2 Msamples/s (263 ksamples/s per channel), Maxim's MAX1316, MAX1320, and MAX1324 squeeze twice as many channels as competing devices into half the package footprint (49 mm2 versus 100...
Controlling Distributed Power
Sponsored by: POWER-ONE
Because of their high transistor density and thin gate oxides, the latest high-performance microprocessors, FPGAs, and ASICs combine low operating voltages with currents that swing rapidly from milliamps to tens of amperes and back. To accommodate...
16 Bits, Buffers, And Voltage References All Squeeze Into SOT-23-Packaged DACs
Homing in on industrial-control and T&M applications, Analog Devices has extended its portfolio of small-footprint nanoDACs. Eight pin-compatible 12- to 16-bit digital-to-analog converters (DACs) now enter the fray, some for closed-loop...
Dual-Input, 8-Bit, 1-Gsample/s Fold-And-Interpolate ADC Wrings 7.5-Bit Effective Number Of Bits From 1.6 W
At $219 each in 1000-unit volumes, the ADC08D1000 analog-to-digital converter (ADC) isn't destined for consumer products. But this chip from National Semicondctor can digitize two input signals to 8-bit resolution at sampling rates up to 1...
What's All This "Selective Fit" Stuff, Anyhow?
Back in the late 1950s, George A. Philbrick Researches would cheerfully sell you a $22 K2-W op amp that would swing ±50 V as its rated output (per my old column*), and for $33, a K2-X that would swing ±100 V of output. But there were...
What's All This Pease-Cohen Effect Stuff, Anyway?
Back in 1965, I designed one of the best op amps in the world, the PP25A. It had less than 1 mV of VOFFSET, and 150 pA of IBIAS, using good Amelco n-channel JFETs. Its yellow epoxy package had an impedance far above 1...
CCDs Power High-Definition-Video Camcorder
Purported to bring professional-quality video in the palm of your hand, Sony's HDR-FX1 Handycam camcorder records and plays back high-definition video with 1440 pixels by 100 interlaced lines of resolution. It's powered by the company's...
Cell-Phone Handset Design
Sponsored by: ANALOG DEVICES
Designing a cell-phone handset is a complex, multifaceted project with many issues that extend from the black art of RF design to efficient software development and virtually all other electronic specialties in between. Here are the basic design...
Hardware Algorithm Fine-Tunes Converters For Best Compression
Future analog-to-digital converters (ADCs) that implement Samplify Systems' latest algorithm could compress digitized, band-limited signals by adapting to the signals' bandwidth and dynamic range. With it, designers would be able to stream...
Development Board Shortcuts FPAA-Application Design
Designers or students who want to explore the possibilities of Anadigm's field-programmable analog arrays (FPAAs) can now do so with a development platform from Servenger LLC. The company's PAM-5000R Programmable Analog Module (PAM) is...
ADCs Look To Bring HDTV To U.S. Cell Phones
HDTV on a 2-in. screen? Such a concept may challenge North American readers as the ultimate example of putting 10 pounds of goods in a five-pound sack. But Europeans, more accustomed to public transit and consistent phone and digital broadcast...
Bob's Mailbox
Dear Bob: There's an error in your recent "Mailbox."* What you "heard" about the 555 timer is a bit off the mark. Your story mixed up the 555 with my work on semicustom ICs, which happened about the same time. If you want the...
What's All This Input Impedance Stuff, Anyhow?
A young teacher went to Temple. Several priests and pharisees asked him questions. They asked trick questions to try to fool him. The teacher very sweetly and correctly answered their many tricky questions. All those present were amazed at the...
Seven-Supplies-On-A-Chip Energize XScale Processor-Based Products
Consumer products that use Intel XScale microprocessors include third-generation smart cell phones, PDAs, and Internet appliances. To power XScale devices, Maxim designed the MAX1586A and B and the MAX1587. They integrate seven high-performance,...
Three IC Makers Rise To Multiple Mobile-Display Lighting Challenges
Lighting in handheld portable devices continues to encourage innovation. For medium-size panels with cold-cathode fluorescent-tube backlights, Fairchild Semicon-ductor's FAN7310 full-bridge pulse-width modulation inverter/driver IC supports...
Dual 100-V Schottky Doubles Current Handling
With twice the current-handling ability (60 A) of typical dual-100-V Schottky rectifiers in the TO-220AB form factor, Vishay Intertechnology's MBR60100CT handles secondary rectification, freewheeling, and polarity protection tasks in 100- to 300-W...

Scaling The 1T DRAM Cell
One-transistor, one-capacitor (1T-1C) DRAM cells have been commercially implemented since at least 1999. They save die area compared to conventional 6-T DRAM cells, use less power, yield better, and exhibit faster access times. Unfortunately, the...
It's A Jungle Up There: Radiation Effects In CMOS Devices
For a place we think of as the ultimate void, space is populated with many high-energy particles that can damage semiconductor devices. There are electrons and protons in the Van Allen belts, galactic cosmic rays (about 85% protons, 14% alpha...
