A 48μW Analog Front End Circuit Design for an Ultrasonic Receiver 0.18μm CMOS
Keywords:
Biomedical, infrared, ultrasonic, wearable device.Abstract
Ultrasonic transducer based sensor systems are
widely used in wearable biomedical applications for indoor
location sensing, tracking and other zonal compliance purposes.
A system used for zonal compliance typically made up with a
zonal transceiver device and a battery powered wearable device
with the associated control logic at each interface. Being battery
powered, the design of analog interface circuit to the wearable
device is significant to overall performance of the system. In this
paper, we present a fully integrated Analog Front End (AFE)
interface circuit for the ultrasonic receiver designed and
fabricated in 0.18μm CMOS. Measurement results shows that
the single chip receiver operating at a centre frequency of 40
KHz reduce the power consumption to less than half over the
discrete version
