Abstract :
A 36 MHz intermediate frequency amplifier (IFAMP) is designed using Chartered 0.35 um CMOS technology. The nonlinear characteristic of IFAMP is analyzed, and the technology of leading compensation and miller capacitance compensation is adopted. The circuit simulation tool is ELDORF which provided by Mentor Graphics. Simulation results show that IFAMP has greater than 28 dB gain, low noise figure (about 1.3 dB at 36 MHz). Furthermore, it can reduce the harmonic distortion efficiently and enhance the dynamic range of input signal.
