| 总结: | The use of ultra-wideband (UWB) in target detection, radar and wireless
connectivity, specifically in the medical world, has attracted a lot of attention.
The concept that the IR-UWB system does not necessarily require carrier
signals is one of its most appealing features. IR-UWB can transmit information
using short Gaussian monocycle pulses. In light of these advantages, this paper
proposes a novel UWB transmitter system which consists of UWB signal
generating circuits and UWB antenna, which work together to create entire
UWB transmitter. It is based on impulses and has a simple architecture with low
power consumption. The proposed transmitter is realized in Cadence tools with
90nm CMOS technology and proposed UWB antenna is simulated using
Advanced Design System (ADS) simulator software. In addition, the transmitter
circuit and the antenna are co-simulated using ADS software. The illustrated
UWB transmitter uses a low-power supply and generates pulse
amplitude with pulse duration of for the Gaussian monocycle pulse. Due
to its increased output voltage swing and reduced power consumption when
comparing to other circuits, the proposed architecture is functional and suitable
for use in short-range wireless networks and medical applications. |
