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.
