Embodiment Construction

[0022] Techniques for calibrating interleaved analog-to-digital converter (ADC) arrays are presented. The transceiver assembly can include an ADC assembly that includes an array of interleaved ADC subassemblies (also referred to herein as sub-ADCs) and an auxiliary path associated with an auxiliary sub-ADC that can be used to compare the auxiliary path signal with the sub-ADCs in the array. ADC signals to facilitate calibrating the sub-ADCs in the array. The auxiliary path can be designed to closely match the processing paths of the other sub-ADCs.

[0023] The transceiver component is capable of receiving a signal (eg, an analog signal) including data from a remote transmitter component (eg, a transmitter, transceiver, or another type of communication device). When the transceiver component receives an analog signal, the interleaver component can interleave the received analog signal on the sub-ADCs in the array, wherein the interleaver component or the calibration component...

Abstract

Techniques for calibrating interleaved analog-to-digital converter (ADC) arrays are presented. The transceiver includes an ADC assembly including an array of interleaved sub-ADCs and an auxiliary path associated with the auxiliary sub-ADCs for facilitating calibration of the sampling array by comparing auxiliary path signals with signals of sub-ADCs in the array. The calibration component uses a phase interpolator and an analog delay line to adjust the auxiliary sub-ADC so that the auxiliary sub-ADC is queued to any sampling instant of the sampling array. The calibration component compares the auxiliary signal to the sub-ADC signal, determines the path difference between the sub-ADC paths based on the comparison, and calibrates the sub-ADC and the sub-ADC paths to reduce the path difference to reduce the number generated by combining the sub-ADCs in the array Distortion in the digital stream produced by combining substreams.

Description

technical field [0001] This disclosure relates to information transfer. Background technique [0002] Communication devices, such as transceivers, can be used to transmit or receive voice data or other data to or from other communication devices. Voice data or other data can be transmitted via wired or wireless communication connections. One trend is to increase the amount of data that can be transferred and the rate at which data is transferred. [0003] As transmission data rates, speeds, and bandwidths increase, the circuits used to send, process, and receive data must also handle high-bandwidth signals. One component used by many systems that use digital signal processing is an analog-to-digital converter (ADC), which can be used to convert an analog signal (eg, a speech signal) into digital form for further digital signal processing. One approach to designing ADCs capable of supporting relatively high bandwidths at high sampling speeds is to interleave ADC arrays (eg...
