The article provides strategies on how to tweak the features of a microcontroller (MCU) to enhance the resolution of an embedded alternate/direct current or A/D converter (ADC) with the use of the MAXQ2010 software. It examines the frequency-domain transfer function of a multibit ADC and ...
AN5537 Application note How to use ADC Oversampling techniques to improve signal-to-noise ratio on STM32 MCUs Introduction All STMicroelectronics microcontrollers embed an ADC (analog-to-digital converter) with a given resolution (number of bits) and sa...
There are times when a customer design demands a resolution higher than the ADC of the selected device. This application note describes how an oversampling method can be incorporated to increase ADC resolution past the currently available number of bits. This can help reduce the cost in building...
AN2668 Application note Improving STM32F1 Series, STM32F3 Series and STM32Lx Series ADC resolution by oversampling Introduction The STMicroelectronics STM32F1 Series, STM32F3 Series and STM32Lx Series Cortex®-M3 based microcontrollers embed a 12-bit enhanced ADC, sampling with a rate up to ...
(ADC),simplify the circuit of system and reduce the cost, oversampling technique was applied to increase ADC’s resolution while making full use of the speed of ADC. Moreover, addition of the shaped function was applied, and then oversampling was utilized to detect the weak signal. ...
The average method is often used to smooth and remove speaks from the input signal. Note that normal averaging does not increase the resolution of the conversion because the sum of m N-bit samples divided per m is an N-bit representation of the sample. 6/21 AN2668 Oversampling using ...
I'm new to FPGA's. I need to increase the resolution of an 8bit 40Msps ADC through oversampling. I would just like to know if it is possible to implement this on a cycloneII. If anyone also knows how to go or give me tips on how to increase the resolution through decimation that...
Using an ADC with more bits makes the the minimum step size (LSB) smaller to give higher resolution. The Arduino Uno is fixed at 10 bits but there is a way of increasing the number of bits through a clever process of aceraging and decimation; See this page:Arduino ADC oversampling. ...
combination to increase the dynamic range available from an ADC. Oversampling improves signal to ...
This technique can therefore be used effectively to increase the dynamic range of the ADC at the expense of overall output sampling rate and extra digital hardware. It should also be noted that averaging will not correct the inherent integral nonlinearity of the ADC. Now, consider the case of ...
