    Debugging an integrated ADC in a microcontroller using an oscilloscope

    You probably don’t reach for an oscilloscope first when debugging an analog-to-digital converter (ADC) integrated into a microcontroller (MCU). But an oscilloscope can help you make sure that the ADC operates as expected. In this blog post, I’ll use the C2000™ Piccolo™ F28027 MCU as an example to show you how. The precise...

    Transimpedance amplifier designs for high-performance, cost-sensitive smoke detector applications

    This post is co-authored by Collin Wells . Photodiode-based light sensing is a common technique where operational amplifiers (op amps) are used to condition a photodiode sensor for a wide range of applications. An example of this is in smoke detectors, where a photoelectric smoke alarm is used to identify the presence of smoke in the chamber. ...

    How to deliver clean USB Type-C™ signals

    The rapid growth of USB Type-C enables a unified interface to deliver data, video, audio and power through a single connector. USB Type-C ™ not only supports the latest USB data rate of 10Gbps, it also enables up to 100W power delivery through the same cable carrying the data traffic simultaneously. Type-C has reversible plug orientation; it also...

    How to implement FM modulation

    For most people, listening to frequency modulation (FM) radio is a part of their life. But what is FM exactly? It’s simply a popular modulation scheme used to embed information on a high-frequency radio carrier. The hardware requirements for im...

    Do-it-yourself: Three ways to stabilize op amp capacitive loads

    Capacitive loads can cause stability problems in operational amplifier (op amp) circuits, resulting in large overshoots, ringing, long settling times – and in severe cases, sustained oscillations. These issues occur because the capacitive load ...

    Big USB Type-C™ protection for your small application

    We’re starting to get used to seeing the USB Type-C™ connector on laptops and even set-top boxes, but as it makes its way into small form-factor applications like mobile phones, wearables or other portable electronics, system designers have different design considerations. Their challenge is how to take advantage of a world of new features...

    “Trust, but verify” SPICE model accuracy, part 1: common-mode rejection ratio (CMRR)

    SPICE simulation is an immensely valuable tool that allows engineers to have high confidence in their analog designs before ever stepping foot in a lab. While many of us live and die by our simulation results, have you ever stopped to question if you...

    Why should you care about the noise immunity of MLVDS drivers and receivers?

    Noise immunity is the ability of a device or system to suppress external noise, and to function – without deteriorating in performance – in the presence of noise. Multipoint low-voltage differential (MLVDS) devices are used widely in wire...

    Be smart: select digital isolators for your smart meter

    (Vikas Kumar Thawani co-authored this blog post.) All major countries are investing in the smart grid and are committed to making it a success. Why? Because power demand is going up, grid and power distribution will be critical. As demand increases, the cost of power increases because the resources to generate electricity are limited, resulting in...

    High speed data converter clocking for JESD204B

    The JESD204B standard for data-converter clocking simplifies board routing, but puts some requirements on the device that clocks the data converter. One such requirement is the SysRef pulse that is sent to multiple data converters in order to mark a ...
