摘要

本文提出了一种不同于传统的直接δ - σ接收机的新设计。该接收机设计用于覆盖0.4 GHz至3.6 GHz的频分双工(FDD)频段，可配置带宽为3.84 MHz (WCDMA)和9.0/13.5/18/37 MHz (LTE-10M/15M/20M/37M)。接收机符合3GPP规范，噪声系数(NF)为2.5dB，带内(IB)三阶截距点(IIP3)为-15dBm，带外(OOB) IIP3为OdBm，峰值信噪比(SNDR)为58dB。该电路采用CMOS 65nm设计，在1.2 V电压下功耗为70 mA。

A 5th-order Configurable-Frequency Direct Delta-Sigma Converter for Mobile Application

This paper presents a novel design of direct delta-sigma receiver, which is different from conventional design. This receiver is designed to cover Frequency Division Duplex (FDD) bands from 0.4 GHz to 3.6 GHz with a configurable bandwidth of 3.84 MHz (WCDMA), and 9.0/13.5/18/37 MHz (LTE-10M/15M/20M/37M). The receiver complies with 3GPP specification while performing Noise Figure (NF) of 2.5dB, Inband (IB) Third-order intercept point (IIP3) of -15dBm, Out-of-band (OOB) IIP3 of OdBm and peak Signal-to-Noise-and-Distortion ratio (SNDR) of 58dB. The circuit is designed in CMOS 65nm, and the power consumption is 70 mA at a voltage supply of 1.2 V.
