摘要

提出了用于胶囊内窥镜高数据速率医学成像的二相移键控(BPSK)调制器。BPSK调制器由混频器和环形振荡器组成。环形振荡器提供433MHz的载波频率，与混频器混合产生BPSK调制信号。该调制器采用Silterra 0.13μm CMOS工艺设计。电源电压为1.2 V，数据速率为3.5Mbps时，混频器功耗为1.2 mw，输出功率为−10.7 dBm。

Low power BPSK modulator for the application of capsule endoscope

This paper presents the Binary Phase Shift Keying (BPSK) modulator for high data rate medical imaging for capsule endoscope. The BPSK modulator consists of a mixer and a ring oscillator. The ring oscillator provides carrier frequency of 433MHz and mix with the mixer to produce BPSK modulated signal. The modulator is designed using Silterra 0.13μm CMOS process. For supply voltage of 1.2 V, data rate of 3.5Mbps the mixer has power consumption of 1.2mW and at output power of −10.7 dBm.
