Abstract
A circuit for implementing a time-interleaved analog-to-digital converter is described. The circuit comprises a sampling clock generator configured to receive a reference clock signal having a first frequency. The sampling clock generator has a first stage sampling clock generator configured to generate a first plurality of clock signals based upon the reference clock signal and having a second frequency, and a second stage sampling clock generator configured to generate, for each clock signal of the first plurality of clock signals, a second plurality of clock signals having a third frequency; a first stage having a plurality of switches configured to receive an analog input signal, wherein each switch of the plurality of switches is controlled by a corresponding clock signal of the first plurality of clock signals; and a second stage having a plurality of analog-to-digital converter banks, each analog-to-digital converter bank having a plurality of analog-to-digital converters and configured to receive the analog input signal by way of a corresponding switch of the plurality of switches.
