| description | A negative impedance converter (NIC) is an active 2 port network that generates non-foster
elements such as negative capacitor or inductor. It can be realised using transistors or
operational amplifier (op-amp). In this report, 2 different topologies of op-amp based NIC
were discussed and, in the process, a formula that governs the input impedance of these
topologies was developed based on observations. This formula can be used to analyse and
account for the differences between these topologies.
First, the derivation of the formula using ideal op-amp with finite gain will be presented,
followed by the verification of this formula. Next, an attempt to extend this formula to
nonideal op-amp is made. Although the nonideal op-amp formula has yet to be developed, the
strong connection with the parameters found in the ideal op-amp formula may serve as a
steppingstone towards developing the nonideal op-amp formula. This would help in
designing the desired non-foster element for real life application. |
