Patent attributes
The present invention provides an active inductor apparatus and system, having a variable frequency response through inductance adjustment. The active inductor apparatus comprises a variable resistive element and a variable gain element, and the system further comprises an inductance controller and a gain controller. The variable resistive element has a first terminal and a second terminal, with the second terminal capable of receiving a first adjustment signal. The inductance controller is capable of providing the first adjustment signal to control and adjust a resistance level of the variable resistive element. The variable gain element has a third terminal capable of receiving a second adjustment signal. The gain controller is capable of providing the second adjustment signal to control and adjust a transconductance of the variable gain element. The frequency response of the active inductor apparatus and system is variable in response to adjustment of the resistance level of the variable resistive element and in response to adjustment of the transconductance of the variable gain element.
