Demystifying Why Your Embedded ADC Does Not Perform To The Datasheet And What You Can Do To Improve Performance
Noise is a complex problem that challenges even the most experienced analog engineer working with sensor nodes in IOT. The complexity comes from the number and types of noise sources. These sources can be within the microcontroller (MCU), on the board, or in the environment. As MCU integration increases and speeds increase the internal noise has increased. Additionally, the rise of IOT and wireless connectivity has increased the noise in the environment. This paper will educate the reader on why the datasheet doesn’t tell the whole story of integrated performance and generally represents a subset of use cases. This subset represents characterization of singular peripherals and functions with the remainder of the SOC peripherals and functions in a sleep or idle state. This paper will show data from real world examples implementing different techniques to reduce noise. These examples will include noise introduced by SPI and sub-1GHz wireless connectivity which will be generalized to I2C and UART as well as BLE and WIFI. Using specific use cases and showing how to generalize to other wired or wireless configurations, MCU developers can apply the concepts discussed in this paper to successfully integrate precision analog measurements in their sensor node designs.
