News and design information for analog design engineers, including those working on signal-chain, power, interface, and RF issues.

  • Exploiting subthreshold MOSFET behavior in analog applications

    Robert Chao, Advanced Linear Devices Inc, February 2, 2012
    You can now spin MOSFETs’ “unusable” leakage current into “gold.”  More
  • Balancing GBWP and quiescent current for dissipation optimization

    Namrata Pandya, Microchip Technology Inc, February 2, 2012
    Minimizing power dissipation in analog applications requires a careful balance between GBWP and quiescent current.  More
  • Small-signal bandwidth in a Big Bandwidth era

    Bill Laumeister, Maxim Integrated Products Inc, February 2, 2012
    Understand the interplay between bandwidth and op-amp specifications.  More
  • Parallel resonance

    Howard Johnson, PhD, February 2, 2012
    A scene that involves pushing a child on a swing helps explain the concept of resonance.  More
  • Stable pulse generator uses matched transistors in a current mirror

    Bill Morong, Paoli, PA; Edited by Margery Conner and Fran Granville, February 2, 2012
    Inexpensive dual transistors work as well as do legacy matched pairs.  More
  • Implement an audio-frequency tilt-equalizer filter

    Francesco Balena, Electro-Acoustic Design, Conselve (PD), Italy; Edited by Margery Conner and Fran Granville, February 2, 2012
    Developing the transfer functions lets you customize the filter.  More
  • Circuit provides 70 dB of AGC

    Ben Segal, Telecommunications Technology, Sunnyvale, CA; Edited by Margery Conner and Fran Granville, February 2, 2012
    A comparator autoranges to ensure that the automatic-gain-control section sees a signal between −60 and −25 dBm, keeping the FET in its linear region.  More
  • Sorting out 4G: Are we there yet?

    Janine Love, Contributing Editor, January 30, 2012
    Thanks to clever marketing campaigns and branding, the general public believes that 4G has arrived. The performance of 4G/LTE mobile handsets has improved, and designers are pushing the outer limits of performance in all parts of the handset. In many cases, the limitation is available spectrum, so designers must develop creative approaches until governments act.  More
  • TI ups its smart grid offerings

    Nicolas Mokhoff, EE Times, January 23, 2012
    Texas Instruments claims the industry's first demonstration of a radio frequency system-on-chip that integrates an IEEE 802.15.4 (2.4 GHz) radio, an ARM Cortex-M3 processor, and enough flash and RAM to run the ZigBee IP stack and SE2.0 profile.  More
  • Analog design in the 21st century: challenges, tools, and IC advances

    Steve Taranovich, Contributing Technical Editor, January 19, 2012
    Analog-circuit-design engineers overcome new challenges with advanced tools and ICs.  More
