Squeeze 10-Bit Performance From An 8-Bit ADC, Part 1: Additive Dithering

What’s the cost of an underused hardware resource? If you spec your microcontroller to have a 10-bit analog-to-digital converter (ADC) but only require 8 bits, you’ve paid for extra performance that ...

8-bit microcontroller implements digital lowpass filter

Filtering occurs frequently in the analog world. Unfortunately, in the digital world, engineers apply it mainly to the DSPs (digital-signal processors) and not to the small 8-bit microcontrollers that ...

Squeeze 10-Bit Performance From An 8-Bit ADC, Part 2: Triangular Dithering

Part 1 of this column (ED Online 18899) showed how designers can use additive dither and oversampling to increase the resolution of an analog-to-digital converter (ADC). In this edition, we will ...
