Abstract

In this paper, we describe a 900MHz CMOS RF transceiver using an ISM band for ZigBee applications. The architecture of the designed rx front-end, which consists of a low noise amplifier, a down-mixer, a programmable gain amplifier and a band pass filter. And the tx front-end, which consists of a band pass filter, a programmable gain amplifier, an up-mixer and a drive amplifier. A low-if topology is adapted for transceiver architecture, and the total current consumption is reduced by using a low power topology. Entire transceiver is verified by means of post-layout simulation and is implemented in 0.18um RF CMOS technology. The fabricated chip demonstrate the measured results of -92dBm minimum rx input level and 0dBm maximum tx output level. Entire power consumption is 32mW(@1.8VDD). Die area is $2.3mm{\times}2.5mm$ including ESD protection diode pads.

본 논문은 ZigBee 응용을 위한 900MHz ISM 밴드용 RF 송 수신기 설계에 관한 기술이다. 수신단은 저잡음 증폭기, 하향믹서, 프로그래머블 이득증폭기, 밴드패스필터로 구성되며, 송신단은 밴드패스필터, 프로그래머블 이득증폭기, 상향믹서, 구동증폭기로 구성된다. 송 수신단은 Low-IF 구조를 사용하였다. 또한, 송 수신단을 구성하는 각각의 블록은 저전력 기술을 사용하여 전체적인 전류 소모를 줄였다. Post-레이아웃 시뮬레이션으로 전체 송 수신기의 성능을 검증하였으며, 0.18um RF CMOS 공정을 이용하여 칩으로 구현하였다. 측정결과 제작된 칩셋은 -92dBm의 최소 수신 입력 레벨을 갖으며, 0dBm의 선형적인 최대 송신 출력 레벨을 갖는다. 또한, 전력 소모는 32mW(@1.8VDD)이며, ESD 방지 다이오드 패드를 포함한 칩 면적은 $2.3mm{\times}2.5mm$이다.
