Shutting out the noise: Voltage references for precision analog signal paths in space applications - Story
October 08, 2014
When designers are trying to select a component in the signal path of a satellite system, it is often difficult to find a device with both the radiation tolerance and accuracy required. Signal integrity is, after all, the key specification when designing an analog signal chain. The main causes of error to the integrity of the signal chain can be divided into two categories: inaccuracies due to noise and inaccuracies due to shifts in voltage. While it is important to consider all components in the signal path, one component is the most critical in achieving precision performance: the voltage reference.
