What this episode covers

Dave Jones, known as the 'Filter Wizard' and former audio specialist at Burr-Brown and Cypress, discusses the evolution of analog filtering from discrete components to integrated circuits. He explains how the shift to Delta-Sigma ADCs reduced the need for external analog filters in audio, while high-speed digital interfaces have reintroduced analog design challenges like signal integrity and trace roughness. Jones emphasizes that power supply quality, clock jitter, and physical PCB layout are critical factors in high-performance design, often overlooked by engineers who rely solely on simulation. He advocates for rigorous system-level thinking and understanding the physics of signals rather than just applying empirical fixes like adding capacitors.

    379: Monstrous Cable Corporation

    Tom Anderson, an engineer at Keysight Technologies, discusses the practical realities of embedded hardware for new college graduates, focusing on the nuances of floating I/O pins, tri-state outputs, and latch-up failure modes. He explains the behavior of inductors in switching power supplies and relays, the importance of pull-up/pull-down resistors, and the differences between ADC types, sampling rates, and bandwidth. Anderson advocates for learning from vintage technical literature, such as TubeBooks.org and 'The Art of Electronics,' and shares his methodology for analog circuit design using symbolic algebra and system-level constraints.

    Hosts Carl and Corey discuss the 'paralysis of analysis' in embedded electronics, focusing on strategies to navigate component selection hell and avoid design rabbit holes. They advise defining strict parameters before searching distributors like Digi-Key, prioritizing critical specs, and leveraging evaluation boards to test parts like instrumentation amplifiers in real-world conditions rather than relying solely on simulation. The conversation also covers PCB layout pitfalls, such as obsessing over trace aesthetics (OCD layout) and stack-up decisions, urging engineers to prioritize electrical functionality and consult with PCB fabrication houses for impedance and via sizing.
