Abstract
A pipelined ADC includes a first sub ADC and a second sub ADC. The second sub ADC is configured to receive, as an input, an analog residue generated by the first sub ADC. The first sub ADC is configured to operate in a first conversion phase, generating a digital output of the first sub ADC, and a second conversion phase, generating the analog residue. The first sub ADC includes a reference-voltage generator circuit configured to generate a reference voltage of the first sub ADC and having a first mode of operation and a second mode of operation, in which the noise power of the reference voltage is less than in the first mode of operation. The reference-voltage generator circuit is configured to operate in its first mode of operation in the first conversion phase and in its second mode of operation in the second conversion phase.
