If you use the analog inputs of your favorite microcontrollers, sooner or later you have needed to check their linearity and accuracy over the entire range of input values. This precise and compact ...

Engineers always want to get all they can from their circuits; this holds for analog-to-digital converters (ADCs). To maximize performance from an ADC, resolution is perhaps the primary spec to focus ...
