“…Continuous in situ monitoring and long term reliable operation of the system are the key features of any implantable sensor system. Recent technological breakthrough of micro-and nano-fabrication processes have led to the development of various miniature, light weight, cost effective and energy efficient sensors for biomedical applications such as monitoring of glucose [2] [3], lactate [4], pH [5], carbon dioxide (CO 2 ) [6], oxygen (O 2 ) etc. Variation of sensor signal requires an electronic circuit to convert the changes in sensor signal into a digital data and transmit the data outside of the biological environment for further diagnostics and processing.…”

Healthcare providers are depending on remote patient monitoring system more and more to treat a patient before the conditions become acute. Low-power electronics is an integral part of the remote patient monitoring system which is required for data acquisition, signal processing and data transmission. This work reports a low-power digitally controllable current readout circuit and a modulator unit designed for remote patient monitoring system. The current readout block converts current (0.2 μA to 5 μA) from biosensors to a data signal whose frequency is proportional to the sensor current. A switched capacitor based modulator is realized which modulates the data using a low-power digital modulation scheme. The current readout and the modulator units are digitally controllable to save power and to provide either ASK or FSK modulated output signal. The circuit is simulated using a 0.35-μm standard CMOS process and it occupies less than 0.053 mm 2 of chip area. Power consumption of the circuit varies from 44 μW to 57 μW for 0.2 μA to 5 μA input current with 1.5 V supply, which is very attractive for biosensor applications.
