Now I'm designing the output part of LNA and I found little literature focused the output design of LNA. The following are my questions:
1) The LNA will be connected to the next stage. How to include the next stage input impedance when I simulate LNA using SpectreRF?
2) I use the shunt peaking technique for output design. The gain will be gm*RL*Q. In the output part, C represents the whole capacitance including output capacitance of transistor, parasitics and next stage input capacitance. How can I decide the value of L and R?
Please help me. Thanks a lot!
