An ASK-Based IF Receiver for Wireless Endoscopy Capsule Systems
-
Abstract
This paper presents a low power ASK IF receiver for wireless endoscopy capsule systems.The receiver includes an AGC loop that compensates the channel attenuation,an ASK demodulator,and a band-gap based bias circuit.The IF-circuit was implemented in a 0.25μm CMOS process.Tests show that the IF receiver can correctly detect digital base-band signals from -30～10dBm IF signals with an IF operating frequency of 20MHz.The receiver draws about 2.1mA of current from a 2.5V power supply.-
