Ease 8-bit microcontroller programming with a simple formula to calculate hex values of ADC output. Harry Gibbens Jr, Deafworks, Provo, UT; Edited by Charles H Small and Brad Thompson -- EDN, 4/12/2007 This Design Idea is for low-end, eight-pin, flash-memory, 8-bit microcontrollers, s...
SNR is a comparison of the noise to be expected with respect to the measured signal. The noise measured in an SNR calculation doesn't include harmonic distortion but does include quantization noise (an artifact of quantization error) and all other sources of noise (for example, thermal noise)....

TIP: You can select theinternal 1.1V referenceand this will give a step size of about 0.1V: Exact calculation is 1.1/1024 = 0.00107V ~0.11mV per step . This does mean the ADC can't read voltages above 1.1V - they will just return 1023. ...

This clock is, in turn, routed through a programmable clock divider from which the MCU core clock operating frequency is generated. The microcontroller core is an 8052 and is compatible with an 8051 instruction. 8 kBytes of nonvolatile Flash/EE program memory are provided on-chip. 640 bytes ...
ASRC implementations: (a) programming the ratios and (b) on-chip calculation of the ratio. Thus, in any form, the ASRC technique enables signal chain designers to granu- larly set fodr and go beyond the age-old restriction of limiting fodr to the integer or fractional ratio of the input...
A useful way of determining noise in an ADC circuit is to examine the SNR (see Figure 5). The SNR is the ratio of the root VREF Capacitive Conversion Network mean square (RMS) of the signal power to the RMS of the noise power. The SNR of the FFT calculation is a combination of ...
The external capacitor is calculated based on the following calculation. Assuming that the Cin is charged from Cext fully, this will result in a charge re-distribution. Assuming that the entire charge is supplied from the Cext, we should not let the Cext voltage drop below 1LSB of the ...
