Abstract
A filter circuit uses a trans-conductor circuit coupled to a control circuit having similar characteristics as the trans-conductor circuit. The control circuit is used to set and/or control the quiescent voltage of the trans-conductor circuit. As a result, the trans-conductor circuit may be designed to operate across a large frequency range while consuming minimal power. The control circuit may be operated using direct current (dc) voltage and may be implemented similar to the trans-conductor circuit implemented in the filter circuit.
