Hybrid pi model

amp hybrid pi-model where the input stage of the amplifier is a resistor. The voltage across that resistor is sensed by the gain stage, etc. The simulation time of this type of model is significantly faster than the first macromodel design method; however, the op amp performance is compromised to a great extent with this approach..
