This work proposes a potentiostat circuit for multiple implantable sensor applications. Implantable sensors play a vital role in continuous in situ monitoring of biological phenomena in a real-time health care monitoring system. In the proposed work a three-electrode based electrochemical sensing system has been employed. In this system a fixed potential difference between the working and the reference...
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...
Remote diagnostics of patient's vital information and initiation of necessary actions have resulted in the development of wireless body area network (WBAN). For almost zero maintenance of each sensor node within a WBAN, each node must work with a power consumption less than 100μW which can be achieved employing impulse radio architecture. In this work a low-power transmitter has been presented. The...
The prolific growth of portable electronic devices (PED) has generated tremendous interests among researchers to develop programmable phase-locked loops (PLLs) because of their abilities to produce multiple spectrally pure output frequencies from a fixed frequency oscillator. The power consumption of the RF block of a PED is mostly dominated by the programmable PLLs which are widely used in the design...
