low noise amplifier
Introduction : THE LNA is the block entrusted to amplify the weak signal received by the antenna in a reception system. In wireless systems with high requirements, the LNA design is critical because it should provide enough gain to the low power signals that arrive at the antenna, not degrade the signal-noise ratio , and be capable to sustain large signals with low distortion and low power dissipation. Additionally, since the previous stage of the LNA is an antenna or a filter, a specific input impedance (50 ohm) to guarantee the maximum power transference is needed. In this way, the LNA design implicates a commitment among enough gain, low noise figure, input (and sometimes output) matching, high linearity, and low power. A clear strategy to LNA RF CMOS design that involves the optimization of the noise and linearity performance with a specified gain and power dissipation is not available in the literature. In the last years, large number of LNA circuits in RF CMOS has been presented, however, few accurate methodologies have been proposed. Since the LNA dominates the global noise figure of a receiver, almost all the methods are based on the optimization of the noise performance with predefined gain and power dissipation, meantime the other parameters are adapted to the specifications using simulations and interactive procedures. The linearity performance as a direct objective of design is important for broadband LNAs used in multi-standard systems and for applications The noise performance of a LNA is directly related to the input matching circuit. Different circuit topologies have been proposed with the purpose to match the input for maximum power transfer taking into account the trade-off of a reduced noise contribution. The common source stage with inductive degeneration similar to the topologies often used in LNAs, showed the best noise performance in CMOS . However, other designers have tuned the input impedance that minimizes the noise figure using the classic noise theory
