I need your help, the problem is how to do hand-calculation of return loss S11, I got simulated result of S11 Using ADS. but I need to do hand-calculation to compare each other. please help me!!!
Input impedance to 50 Ohm then annulling the capacitance impact of M5 and M7 another elements are optimized. Using the abowe circuit, the analysis of the input return loss (S11) of the input matching network is given in Equation
