چکیده    With regards to wireless receiver systems, the effects of noise from all the following phases can be reduced using the gain of the lownoise amplifier (lna). therefore, boosting the specified signal power without adding a lot of noise and distortion will be necessary for the signal to be retrievable in the later phases or stages of the system. the proposed method in this study for noise reduction is based on the combination of two techniques: reversed phase noise signal and nonreversed phase signal. the theoretical model for noise cancellation is presented along with the equations for the overall noise value, which are derived based on a twoport model. the circuit design is implemented using the  technology on a cadence spectre rf tool. the current study also implemented a cmos uwb lna configuration with interstage matching as well as shuntseries inductive peaking. this design uses inductive source degeneration cascode technology along with an interstage matching network. moreover, to boost impedance matching and power gain, a chebyshev band pass filter is placed at the input while a shuntseries inductive peaking is placed at the output.

Abstract    With regards to wireless receiver systems, the effects of noise from all the following phases can be reduced using the gain of the lownoise amplifier (LNA). Therefore, boosting the specified signal power without adding a lot of noise and distortion will be necessary for the signal to be retrievable in the later phases or stages of the system. The proposed method in this study for noise reduction is based on the combination of two techniques: reversed phase noise signal and nonreversed phase signal. The theoretical model for noise cancellation is presented along with the equations for the overall noise value, which are derived based on a twoport model. The circuit design is implemented using the  technology on a Cadence Spectre RF tool. The current study also implemented a CMOS UWB LNA configuration with interstage matching as well as shuntseries inductive peaking. This design uses inductive source degeneration cascode technology along with an interstage matching network. Moreover, to boost impedance matching and power gain, a Chebyshev band pass filter is placed at the input while a shuntseries inductive peaking is placed at the output.
