Implantable Devices with Reconfigurable Biosensing Analog Front End

Abstract

This paper, have a tendency to develop a reconfigurable analog front end for wireless body sensing element nodes and implantable devices with reduced size. By converting voltage in to current the effort to achieve the area efficiency is taken. Because these are bio implantable chips if the numbers of transistors are reduced it will reduce lots of power and area, the circuit operation is also quick. In the proposed system, narrow swing current mirror circuit is used in the low pass filter region. By using the current mirror the same input current can be obtained at the output. At the same time the area of the chip used in the devices gets reduced. The active space of the chip is 157µm2.
