differential_low_noise_amplifier

hello everyone,
i am trying to design differential LNA but to start with design i m facing problem however it is a stupid question to ask but i m confused how to use ports for two inputs specifically how to give inverted signal for the second input using psine source. pls help

Dear gaurav_vaidya
Hi
Can you tell me a bit more explanation about what you want to do , exactly , please ?

For Goldsmith,
sir as for any differential amplifier we need one input to be inverted but in case of low noise amplifier we gives inputs at the port in terms of power ( input power handling capacity that is say -20dBm). I am giving one input as -20dBm but confused how to give input power for other differential input.

low noise amplifier

Building differential amplifier is a type of electronic amplifier that amplifies. You are designing with new thoughts and should follow some formula.
