% Opamp gain-Bandwidth
fun = 36; % MHz
% Load Capacitance
CL = 500; % pF
VDD = 3; % V
% Total DC Current pulled from VDD
Ibias = 100; %uA
Itot = 5*Ibias;% uA
% Total power consumption from VDD
P = VDD*Itot/1000 % mW

% Compensation Capacitor
Cc = 5; % pF
% Slew Rate Calculation
SR =  Ibias/Cc % V/us

%% FoM Parameter Calculation
% FOM_S
FOM_s= fun*CL/P

% FOM_L

% IFOM_S
I_FOM_s = (fun*CL/Itot)*1000

% IFOM_L
I_FOM_l = (SR*CL/Itot)*1000
