Pediatric Size Swallow-able Glass Pill for
Digestive Motility Analysis
Digital pill is
basically a multichannel sensor used for remote biomedical measurements using
micro technology. This is used for the real-time measurement parameters such as
temperature, pH, conductivity and dissolved oxygen. The sensors are fabricated
using electron beam and photolithographic pattern integration and were
controlled by an application specific integrated circuit (ASIC).

EXPERIMENTAL RESULTS
The layout of the custom integrated circuit,
which is fabricated on UMC 0.18μm CMOS process has a die size of 1.5 mm x 3
mm, is shown in Fig. 8. Approximately half of the silicon area is composed of
the tunable capacitor bank for ensuring the resonant operation against
variations on CMOS fabrication process and coil manufacturing tolerances.
