Implantable Devices with Reconfigurable Biosensing Analog Front End

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.
