Abstract :
A mixed-signal CMOS circuit design of a smart RF ID tag for heartbeat signal extraction is proposed. This smart RF ID tag has been under development for monitoring heartbeat signals from an electrocardiogram (ECG) microsensor and/or a pressure microsensor implanted in a transgenic animal. This tag is remotely powered by RF electromagnetic induction. The signal packet consisting of an identification code of 64 bits in length and a spike-pulse sequence of heartbeat signals are transmitted to a reader system using BASK modulation.
