Abstract
A biasing system for biasing an electronic circuit includes a resistance connected in series with a transmission line which has a characteristic impedance substantially equal to the resistance and comprises a conductive line and a plurality of current sources distributed along the conductive line. The biasing system can be used as a biasing and/or matching supply for any type of broad-band low-noise power application requiring high bias currents.
Claims11
A biasing system for biasing an electronic circuit, said system comprising a resistance connected in series with a transmission line which has a characteristic impedance substantially equal to said resistance and comprises a conductive line and a plurality of current sources distributed along said conductive line, wherein each current source is configured to maintain a substantially constant current.
A method of manufacturing a biasing system for an electronic circuit, comprising:
- providing the biasing system, wherein the system comprises a resistance connected in series with a transmission line which has a characteristic impedance substantially equal to said resistance and comprises a conductive line and a plurality of current sources distributed along said conductive line, wherein each current source is configured to maintain a substantially constant current;
- and
- selecting the number N of the plurality of current sources, wherein each current source is configured to deliver a current EC and the system is configured to deliver a desired total current TC by calculating N equals TC divided by EC.
