The Near Field Communication (NFC) market is emerging into multiple fields including Medical, Consumer, Retail, Industrial, Automotive and Smart Grid. Card Emulation is one of the three operational mo
This application report describes a method to dynamically increase device frequency in a way that minimizes voltage dips on the board power supply. The PLL’s multiplier can be stepped in 8% steps every 50 reference clocks.
This application note steps through the rework process to convert the TPS2413EVM, HPA227-002, to demo the TPS2419. There is no dedicated EVM for TPS2419.
This application report describes the development of a new low power binaural wearable digital hearing aid platform based on the TMS320C5000(tm) fixed point digital signal processor(DSP). This platform is a real-time system capable of processing two input speech channels at a 32 KHz sampling rate for each channel and driving a stereo headphone output. It provides for frequency shaping noise suppr
This article discusses the thermal noise source of electrocardiogram (ECG) applications basedon the ADS1298 and ADS1298R family of multichannel simultaneous sampling 24-bit delta-sigma (ΔΣ) analog-to-digital converters (ADCs). This report offers several observations on identifying the major sources of thermal noise in an ECG system and makes several recommendations regarding how to improve t
This application report presents a comprehensive collection of the input and output characteristic curves of integrated circuits from various 5-V logic families. These curves go beyond the information given in data sheets by providing additional details regarding the characteristics of the components. This knowledge is particularly useful when for example a decision must be made as to which circ
This application report shows nonlinear methods--with quadratic and cubic equations--to improve the accuracy of the 14-bit analog-to-digital converter (ADC) of the MSP430 family. The methods used differ in RAM and ROM requirements calculation speed achievable improvement and complexity. The influence of the restricted calculation accuracy for 8-bit coefficients is compared to the accuracy of fl
The ultrasonic evaluation of specimens with large microstructures can be difficult because of interference caused by the grains in the material. The split spectrum processing (SSP) filtering technique effectively reduces this type of noise by employing a bank of filters followed by a nonlinear detector that increases signal-to-noise ratios. This application report describes the benefits of imp
