Abstract
Time-interleaved analog-to-digital converters (ADCs) and related methods are disclosed that are based upon multiplying digital-to-analog converters (MDACs). For one ADC embodiment, a sample-and-hold circuit receives an input signal and outputs a voltage that represents the input signal. An MDAC receives the voltage, outputs an N-bit digital value, and outputs a current that represents the voltage. A phased current generator receives the current and outputs time-interleaved currents that are based upon the current. An array of sub-ADCs receive the time-interleaved currents, and each sub-ADC outputs a digital value. The digital values from the array of sub-ADCs are then combined and to output an M-bit digital value. The N-bit digital value and the M-bit digital value provide a digital conversion output for the ADC.
