Time-interleaved analog-to-digital converter

Abstract

An integrated circuit comprises a plurality of integrate-and-hold circuits coupled to a differential input pair, a plurality of analog-to-digital converters (ADCs), and a processing circuit coupled to the plurality of ADCs. Different integrate-and-hold circuits of the plurality of integrate-and-hold circuits are time-interleaved to integrate and hold a differential input signal from the differential input pair during different time periods. Each ADC of the plurality of ADCs is coupled to at least one integrate-and-hold circuit of the plurality of integrate-and-hold circuits and is configured to convert an output signal of the at least one integrate-and-hold circuit into digital data. The processing circuit is configured to arrange the digital data from the plurality of ADCs and output the arranged digital data via one or more digital output channels.
