Abstract

The invention provides a compensation device and method, a storage medium and an electronic device, and the compensation device comprises: a time-interleaved analog-to-digital converter (TIADC) whichis configured to receive an input signal and output an output signal; and a compensation module which is configured to obtain first estimation information of the n-a moment and second estimation information of the n-b moment at the nth moment and obtain third estimation information according to the first estimation information and the second estimation information, wherein the third estimation information is used for indicating the compensation module to compensate an output signal of the TIADC at the (n+1)th moment according to the third estimation information. According to the invention, thetechnical problem that effective error estimation and compensation cannot be performed according to the frequency change of the input signal of the TIADC when the sampling clock mismatch estimator performs mismatch error estimation compensation in the related technology is solved, so that the effect that the sampling clock mismatch estimator can be self-adaptive to the frequency change of the input signal of the TIADC is achieved.

Description

technical field [0001] The present invention relates to the field of electronics, in particular, to a compensation device and method, a storage medium, and an electronic device. Background technique [0002] A Time-interleaved Analog-to-Digital Converter (TIADC) consists of M parallel sub-ADCs, or sub-channels; figure 1 is a schematic diagram of the structure of the M-channel TIADC in the related art, such as figure 1 As shown, the TIADC of the M channel contains M sub-ADCs, where the sampling rate of each sub-ADC is f S / M; figure 2 is an ideal sampling diagram of M-channel TIADC in the related art, such as figure 2 As shown, multiple sub-ADCs in the TIADC are sampled in a time-alternating manner. In an ideal state, the above-mentioned M-channel TIADC can make the sampling rate of the system reach M times that of a single sub-ADC. However, due to the inherent shortcomings of the manufacturing process itself, it is impossible for multiple sub-ADCs to be exactly the sa...
