Communicating with ADCs above 500ksps is tough. Adding another variable such as a level translator or isolator to the SPI communication requires more understanding of timing and modifying hardware and firmware. This application note discusses how to achieve the desired dynamic performance with level translators or isolators.
Certified radio modules enabling the radio data transmission in numerous radio frequency bands and radio standards. The radio modules are designed in a way that the mode of operation can be configured via external host micro controller to meet best the requirements of the underlying application. Nevertheless, there are still cases where an adoption or complete change of the firmware is necessary to enable standalone operation, provide new interfaces or simply to optimize the behaviour of the underlying application. Due to the change in firmware the radio certification of the adopted radio module must be verified again. This application note describes in which cases the certification of an adapted radio module can be created on base of the certification of the Würth Elektronik eiSos standard product.
The ubiquity of wireless communications is driving the need for general-purpose RF amplifiers that are applicable to many categories, from 5G systems to radio and antenna applications.
When designing an RF amplifier, the first step is to define some important parameters such as target frequency and gain factor. By selecting the optimal passive components, the transmission characteristics of the amplifier may be enhanced and improved. A well-designed layout that can transmit RF signals and the DC current to power the amplifier stage on a single line without interference or cross-talk further improves RF performance.
A key component for this interference-free operation of the transmission of mixed signals (RF and DC) is the inductor for decoupling the RF and DC supplies. In addition to the usual approach of using a standard inductor, another suitable alternative is to use a multilayer ferrite. To compare and evaluate the ferrite and inductor in this application, an evaluation board of an RF amplifier was realized and measured. This application note also includes circuit design considerations and various recommendations for achieving optimal parameters using two RF amplifier examples.
The first light source for actuating an optoelectronic photosensor was the tungsten filament or incandescent lamp. It was eventually replaced by the GaAs infrared emitting diode which offered longer life, smaller size, less power to operate and less heat generated. The GaAs LED is still the workhorse of the industry and will continue to be used in steadily decreasing numbers for the next few years. It will eventually be replaced by GaAIAs as the industry standard for two major reasons: GaAIAs offer at least twice the power output at the same input current (IF) level and significantly improved coupling efficiency.

The Proteus-e is a radio module based on the nRF52 Nordic Semiconductors SoC, which provides various Bluetooth LE and has its focus on low power features. This Application Note shows how easy the "transparent mode" can be used to quickly connect the Proteus-e in order to communicate with a Bluetooth LE connection partner (e.g. a smart device). As second step with more advanced functions, and therefore recommended to be used in applications, the reader is introduced to the Command Mode that is also available to be used on the Proteus-e.

The CoreEDAC IP generates Error Detection And Correction (EDAC) circuitry for both internal (on-chip) and external RAM blocks. The user data is fed to the EDAC encoder, which calculates the parity bits and appends these to the user data, forming a codeword. The codeword is stored into the RAM. During user read, the read codeword is decoded first, which detects and corrects errors (if any), discards parity bits, and outputs the corrected user data word. Scrubbing periodically checks every memory location using the ECC decoder. If a location contains a corrupted word, the decoder detects and corrects the word. The scrubbing circuitry then writes the corrected word back to the same location. To provide normal access to the RAM and prevent decreasing performance, scrubbing is only done during idle periods. The scrubbing circuitry sets a proper write address and write enable signals, writing the corrected codeword back to the RAM. Writeback occurs only upon detecting an error.
