Abstract

A multi-band FSK transmitter (Tx) is presented in this paper. The Tx is designed to operate at the ISM frequency bands at 433/868/915 MHz, 2.4 GHz, and MICS band at 402~405 MHz, and supports a data rate well over 1 Mbps. The Tx adopts an analog modulator which allows a deviation frequency ranging from 714 kHz to 3.2 MHz. In addition, this work proposes an inductor-less wideband mixer and a voltage-controlled oscillator to save the chip area. Fabricated in a 0.18-μm CMOS process, the proposed Tx consumes 8.9 mA to 12 mA from a 1.8-V supply voltage at different frequency bands. The measured FSK errors range from 13.9 % to 15.4 %, which are adequate for most low-cost wireless applications. The proposed multi-band Tx occupies an area of 1.6 mm × 1.9 mm.

400-MHz/900-MHz/2.4 ghz多波段FSK发射机，0.18 μm CMOS

本文介绍了一种多波段FSK发射机。Tx设计工作在ISM频段433/868/ 915mhz、2.4 GHz和MICS频段402~405 MHz，支持超过1mbps的数据速率。Tx采用模拟调制器，允许偏差频率范围从714 kHz到3.2 MHz。此外，本工作还提出了一个无电感的宽带混频器和一个压控振荡器，以节省芯片面积。该Tx采用0.18 μm CMOS工艺制造，在不同频段1.8 v电源电压下消耗8.9 mA至12 mA。测量的FSK误差范围为13.9%至15.4%，足以满足大多数低成本无线应用。多频段Tx的面积为1.6 mm × 1.9 mm。
