Patent ID: 8115553

Claim:
A radio frequency wide band amplifier architecture having a noise that does not exceed a threshold value, and a linearity better than a threshold value, said radio frequency wide band amplifier architecture comprising a first stage amplifier and a second stage amplifier, said second stage amplifier comprising: an input source resistor (R in ) that receives an input voltage signal; a feedback resistor (R fb ) directly connected to said input source resistor; a p-type metal-oxide-semiconductor (PMOS) transistor directly connected to said input source resistor, wherein said PMOS transistor receives an output from said input source resistor; a n-type metal-oxide-semiconductor (NMOS) transistor directly connected to said input source resistor, wherein said NMOS transistor receives an output from said input source resistor; and a lumped output resistor (R out ) that receives an output from said feedback resistor, said PMOS transistor, and said NMOS transistor, wherein a terminal of said lumped output resistor is connected to ground, wherein g m equals a trans-conductance of said PMOS transistor (g mp ) plus a trans-conductance of said NMOS transistor (g mn ), and wherein said g m is determined in accordance with equation: g m =g mp +g mn .
