摘要

超低功耗(ULP)接收器可以应用于可穿戴和植入式生物医学传感器。本文采用1.8 V 0.18 μm CMOS工艺，实现了用于低中频FSK生物医学接收机的通道选择滤波器ULP带通滤波器。功耗为200 μW时，测量到的中心频率为1.5 MHz，带宽为330 kHz。应用于低中频FSK生物医学接收机，可实现330 kb/s的数据速率。

A ultra-low power channel selection filter for low-IF FSK biomedical receivers

Ultra-low power (ULP) receivers can be applied in wearable and implantable biomedical sensors. In this paper, a ULP band-pass filter designed as a channel selection filter for low-IF FSK biomedical receivers is implemented in 1.8 V 0.18 μm CMOS process. Under power consumption of 200 μW, the measured central frequency and bandwidth is 1.5 MHz and 330 kHz, respectively. As applied in a low-IF FSK biomedical receiver, data rate of 330 kb/s can be achieved.
