| Summary: | A low power transmitter front end for the
application of a capsule endoscope operating at ISM band of 434
MHz has been proposed. The proposed architecture is aim to
achieve low power consumption which is the essential parameter
in a capsule endoscope. The transmitter front end is implemented
using Silterra 0.13 um CMOS technology and consists of an upconversion
mixer and a voltage controlled oscillator. The current
consumption of the system is 1.57 mA with the supply voltage of
1.2 V. Output power is found to be -14.4 dBm and the phase noise
of the ring oscillator is -81.76 dBc/Hz at offset frequency of 160
kHz. |
