Maximum Power Transfer in Butterworth Van Dyke using Simulated Inductor

摘要

Miniaturization of circuits is the top priority in the digital world. As any basic electronic circuits are developed using the three basic passive elements R, L and C, the compactness of any circuit is possible only when the size of three elements are small. The main element where reduction in size is quiet difficult is the inductor especially at very low frequencies which is possible with the other two. The size of the inductor is heavy at low frequencies and this problem or bottle neck is removed by going in for a simulated inductor. This simulated inductor can be used for all frequencies in any applications. In this paper, an approach to transfer the maximum power to the load is done using simulated inductor. The maximum power transfer theorem emphasizes that the load resistance or impedance satiate maximum absorption of power from the source. The load magnitude each time has an emotional impact on the quantity of power transmitted from the source to the circuit. When the load impedance is very high, then the power delivered to the load is less. The concept of transferring large amount of power to the load holds good for any complex network. A purely resistive load in a network tries to extract maximum amount of power when the load resistance is equal to the source resistance. Hence matching of load to the source resistance is significant in number of applications. A method to transfer maximum power using simulated inductor to a Butterworth Van Dyke load is presented. The simulation is done using Cadence and maximum power is delivered to the load effectively. Python is used to validate the simulated results.
