How to Calculate Input Impedance of Low Noise Amplifier?
Input Impedance of Low Noise Amplifier calculator uses Input Impedance = (1/Transconductance)+Feedback Factor*Load Impedance to calculate the Input Impedance, The Input Impedance of Low Noise Amplifier formula is defined as a measure of how much the FET's channel width changes in response to changes in the gate-to-source voltage. Input Impedance is denoted by Z_{in} symbol.
