application, which is covering a frequency range from 3.1 GHz to 4.9 GHz. LNA is the
first gain element in the receiver architecture. It is designed for Direct Conversion
(DICON). Based on these system characteristics, inductive degenerated common source
LNA was designed using Silterra 0.18 μm process. UWB system with multi band
Orthogonal Frequency Division Multiplexing (MBOA) was chosen over Direct
Sequence Spread Spectrum (DSSS) due to its full optimization of the allocated 7.5 GHz
bandwidth. This LNA consumes 5.9 mA of total current from a 1.8 V dc power supply.
LNA is designed using inductive degenerated common source amplifier, which is
widely used in narrow band design. For UWB application such as wideband matching
was implemented to extend the bandwidths of a narrow band system. In this project,
wideband reactive matching following by LC Chebyshev band pass filter is utilized. The
LC band pass filter utilizes the transformation from low pass network to band pass
network is presented. Impedance and frequency scaling are used in filter transformation
from a low pass filter to a band pass filter. The wideband filter, as input matching
network, is designed on chip for better integration. Three test cases were carried out
using LNA with ideal inductors, ASITIC inductors and SIL18RF inductors. For the
ideal LNA, higher power consumption of 11.25 mW is observed at 1.9 GHz bandwidth,
14.1 dB power gain with gain flatness of ±0.25 dB, input and output match of -10 dB
over its frequency range, noise figure of 2.9 dB and third order intercept point of -6.2
dBm with ideal inductors is . However, using ASITIC inductor, the gain of LNA is
dropped to 13.2 dB with gain flatness of ± 1.5 dB exhibiting higher noise figure of less
than 6 dB with the same input and output matching and comparable third order intercept
point. On the other hand, using SIL18RF inductor, the gain of LNA is further decreased
to 8.5 dB, exhibiting noise figure of less than 4.3 dB with poorer input and output
matching of -9.5 dB and -6.1 dB, respectively. Measurements were carried out on MAX
2654 evaluation kit at a frequency scaling of 1.6 GHz, exhibiting a 9 dB gain, input and
output match of -7 dB and -14 dB, respectively and higher power consumption, 15 mW. |
