Programmable Input Output Resistances of FET Amplifier

The mathematical model provides an insight into the complete behavior of the physical system that reduces the problem to its essential characteristics. The floating admittance matrix (FAM) approach is a neat method of mathematical modeling of electronic devices and its uses in circuits. The zero sum property of the floating admittance matrix provides a check to proceed further or reobserve the first equation itself. Voltage gain, Input & Output resistances are represented as cofactors of the FAM of the circuit. MATLAB plots have been analysed for the functions which lead to an interesting method for improving the Q- factor for the lossy networks which has been proposed in this paper.
