  • How to reverse engineer an analog chip: the TDA7000 FM radio receiver

    In this article, I explain my reverse engineering process, using the Philips TDA7000 FM radio receiver chip as an example. This chip was the first FM radio receiver on a chip.1 It was designed in 1977—an era of large transistors and a single layer of metal—so it is much easier to examine than modern chips. Nonetheless, the TDA7000 is a non-trivial chip with over 100 transistors. It includes common analog circuits such as differential amplifiers and current mirrors, along with more obscure circuits such as Gilbert cell mixers.

    The TDA7000 has seven on-chip capacitors but most of the capacitors in this design are larger, external capacitors: the chip uses 12 of its 18 pins just to connect external capacitors to the necessary points in the internal circuitry.

    The TDA7000 almost didn't become a product. It was invented in 1977 by two engineers at the Philips research labs in the Netherlands. Although Philips was an innovative consumer electronics company in the 1970s, the Philips radio group wasn't interested in an FM radio chip. However, a rogue factory manager built a few radios with the chips and sent them to Japanese companies. The Japanese companies loved the chip and ordered a million of them, convincing Philips to sell the chips. The TDA7000 became a product in 1983—six years after its creation—and reportedly more than 5 billion have now been sold. (I'm a bit skeptical since that is more than the world's population at the time.) Among other things, the chip allowed an FM radio to be built into a wristwatch, with the headphone serving as an antenna. Since the TDA7000 vastly simplified the construction of a radio, the chip was also popular with electronics hobbyists. Hobbyist magazines provided plans and the chip could be obtained from Radio Shack.

  • Forget the 2024 autopsies. Democrats need to be bold — and ruthless - Salon.com

    As the shock has worn off following former Vice President Kamala Harris’ loss to Donald Trump in November, and Trump’s inauguration in January, disillusioned Democrats have been searching for someone or something — anyone or anything — to solve their entrenched messaging and branding failures. Some have even called on former President Barack Obama to fill the void by speaking out forcefully and consistently against Trump. (For his part, Obama has urged Democrats to stop “navel-gazing” and “toughen up.”) Their fruitless search for a solution has revealed a party not just in disarray, but in denial. A recent poll by the Wall Street Journal found only 33% of voters hold a favorable view of Democrats, with 63% expressing an unfavorable view of the party — the most unpopular Democrats have been in 35 years of WSJ polling.

    In a scene worthy of satire, Democratic elites — so-called limousine liberals — are also holding meetings at luxury hotels to solve the riddle of how to speak authentically to “working-class” (white) men. This new strategy even has an acronym, “SAM” — short for ‘Speaking with American Men: A Strategic Plan.’”

    The Washington Post recently reported the “growing consensus” among some party leaders is “that shifting away from a cautious and carefully scripted image is crucial.” Their plan to “project a raw authenticity” seems to be to follow in Trump’s footsteps by lobbing more insults toward Republicans and cursing more, going on more podcasts and recording videos to be broadcast on their social media channels.

    But while the Democrats keep conducting autopsies and churning out plans to be authentic, curse more and find the next Joe Rogan, Trump and his MAGA supporters are rapidly destroying the country’s democratic life. In the face of these threats and autocratic actions, Democrats need to return to fundamentals in their messaging. Trump and his MAGA supporters have spent years — and in some cases, decades — refining their brand, and telling a consistent and superior (if untrue and offensive) story about it. The MAGA movement sees their battle as existential, with Trump as their Christ-figure, a hero and savior, and Democrats as the enemy. This has left Democrats at a serious disadvantage.
