總結: | A new transmitter for ultra-wideband (UWB)
impulse radio is described in this paper. The proposed
architecture features the simple design, low-power operation, and
enables the pulse-shape generation for 2 modulation schemes for a
multi-channel UWB. The average power calculation is presented
for pulse trains using Pulse-Amplitude Modulation (PAM) and
Pulse-Position Modulation (PPM). The design is based on a
0.18-μm CMOS process. The core layout size is only 0.35 mm2.
The simulation results show that the generated signals satisfy the
FCC spectrum mask, and the average power consumption is less
than 1.7mW for these two types of signaling at a 1.8 V supply
voltage. Pulses are transmitted at a PRF (Pulse Repetition
Frequency) of 52MHz in 520 MHz bandwidth channels equally
spaced within the 3.1-10.6 GHz ultra-wideband band. |
