Time-interleaved analog to digital converter based on flash analog to digital conversion

A time-interleaved analog to digital converter, comprising:

• a plurality of capacitor array circuits configured to sequentially sample an input signal and generate a plurality of first residue signals according to a plurality of first quantization signals;
• a flash analog to digital converter circuitry configured to sample the input signal and sequentially generate the plurality of first quantization signals;
• a plurality of first transfer circuits configured to sequentially transfer the plurality of first residue signals from the plurality of capacitor array circuits according to a plurality of first control signals;
• a converter circuitry configured to perform a noise shaping signal conversion according to a first signal in the plurality of first residue signals and a second signal in plurality of second residue signals, in order to generate a second quantization signal;
• a plurality of second transfer circuits configured to sequentially transfer a plurality of second residue signals from the plurality of capacitor array circuits to the converter circuitry according to a plurality of second control signals, wherein the plurality of capacitor array circuits further generate the plurality of second residue signals in response to the noise shaping signal conversion;
• and
• an encoder circuit configured to generate a digital output according to a second quantization signal and a corresponding signal of the plurality of first quantization signals.
