Abstract:	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. 在此篇論文我們以TSMC 0.18μm CMOS 製程實現了一個超低功耗之帶通j慮波器，此帶通濾波器可應用於一超低功耗頻率鍵移接受器之中扮演通道濾波器之角色。此超低功耗帶通濾渡器由一超低功耗低通濾波器與一具低頻傳輸零點之限制器所組成。在200μ 的功率消耗下，此帶通濾波器量測之中心頻率為1.5MHz，頻寬為330 kHz。應用於一低中頻(Low-IF)之頻率鍵移接收器可實現330 kb/s 之資料傳輸速率。
