The Abcs Of Adcs Understanding How Adc Errors Affect System Performance

The Abcs Of Adcs Understanding How Adc Errors Affect System Performance Many design engineers will encounter the subtleties in adc specifications that often lead to less than desired system performance. this article explains how to select an adc based on the system requirements and describes the various sources of error when making an adc measurement. Factors like modulation type, noise, distortion, and peak to average power ratio determine the required adc dynamic range. proper automatic gain control and oversampling can help improve dynamic range performance.

The Abcs Of Adcs Understanding How Adc Errors Affect System Performance Through four different examples, learn about analog to digital converter (adc) system error analysis. We start by establishing our overall system performance requirements. each component in the system will have an associated error; the goal is to keep the total error below a certain limit. often the adc is the key component in the signal path, so we must be careful to select a suitable device. Adcs encounter various origins of inaccuracies and errors, this include offset errors, gain errors, linearity errors, quantization errors, noise, and jitter. each of these factors exerts distinctive influences on the performance of the adc:. So before deciding how many bits are needed, consider system and adc errors such as noise and harmonics and ensure that there’s enough resolution even when error is taken into account.

Understanding adc specifications will also help you in selecting the right adc for your application. we start by establishing our overall system performance requirements. As explained above, by the nature of adc, the device can never duplciated the input signal 100% accurately. there is always a certain difference between each digitized value (output) and the original analog value (input), this difference is called quantization error. The adc performance specifications will quantify the errors that are caused by the adc itself. adc performance specifications are generally categorized in two ways: dc accuracy and dynamic performance. We often think of resistors as noisy devices, but choosing resistor values that are as low as practical can keep noise to a level where system performance is not compromised.
