摘要

本文介绍了一种用于28纳米CMOS无混频器汽车数字音频广播（DAB） III广播无线电接收机的6 ghz连续时间带通（BP） delta-sigma模数转换器（ADC）。BP ADC可以直接数字化从174到240 MHz的整个DAB III频段，而不需要模拟混频器。精确的温度跟踪背景校准保证了过程，电压和温度（PVT）的高接收质量。测量到的IM3为−100 dBc，两个输入音调分别为210和220 MHz。当输入信号为92 MHz时，调频干扰为−101.7 dBc。

A 6-GHz Continuous-Time Bandpass ΔΣ ADC With Background Filter Calibration and −100 dBc IM3 for a Mixer-Less DAB Band III Receiver

This article presents a 6-GHz continuous-time bandpass (BP) delta-sigma analog-to-digital converter (ADC) that has been designed for a mixer-less automotive digital audio broadcasting (DAB) III broadcast radio receiver in 28-nm CMOS. The BP ADC can directly digitize the entire DAB III band from 174 to 240 MHz without the need for analog mixers. A precise temperature tracking background calibration guarantees high reception quality over process, voltage and temperature (PVT). The measured IM3 is −100 dBc with two input tones at 210 and 220 MHz, respectively. FM intrusion with a 92 MHz input signal is −101.7 dBc.

期刊介绍： The IEEE Journal of Solid-State Circuits publishes papers each month in the broad area of solid-state circuits with particular emphasis on transistor-level design of integrated circuits. It also provides coverage of topics such as circuits modeling, technology, systems design, layout, and testing that relate directly to IC design. Integrated circuits and VLSI are of principal interest; material related to discrete circuit design is seldom published. Experimental verification is strongly encouraged.
