Radix-based digital correction technique for two-capacitor DACs

A radix-based digital technique for compensating capacitor mismatch in a two-capacitor DAC is described. Digital input words are pre-distorted with a serial ADC-like algorithm before they are fed into the DAC. The proposed methods provide excellent linearity performance when the DAC is converting a...

Summary:A radix-based digital technique for compensating capacitor mismatch in a two-capacitor DAC is described. Digital input words are pre-distorted with a serial ADC-like algorithm before they are fed into the DAC. The proposed methods provide excellent linearity performance when the DAC is converting a high number of bits. Extra peripheral circuits to achieve the digital compensation are briefly discussed.
