Abstract
A TI-ADC () comprising a group of sub-ADCs (A-A) is disclosed. During operation, M≥2 of the sub-ADCs (A-A) are simultaneously operated for converting M respective consecutive input signal samples of the TI-ADC () from an analog to a digital representation. The total number of sub-ADCs (A-A) in the group is M+N, N≥1. The TI-ADC () comprises error-estimation circuitry () for estimating errors of the sub-ADCs (A-A). Furthermore, the TI-ADC () comprises a control circuit () configured to, for each input signal sample, assign which sub-ADC (A-A) is to operate on that input signal sample. The control circuit () is configured to, for sub-ADCs (A) in a first subset of the group of sub-ADCs (A-A), which are subject to error estimation by the error-estimation circuitry (), perform the assignment according to a first scheme. Moreover, the control N circuit () is configured to, for sub-ADCs (A) in a second subset of the group of sub-ADCs (A-A), which are not subject to error estimation by the error-estimation circuitry (), perform the assignment according to a second scheme, different from the first scheme.
