专利汇可以提供Schottky barrier diode noise generator专利检索，专利查询，专利分析的服务。并且An electrical noise generator employs a Schottky barrier diode operative in the breakdown region as the active noise generating device in a noise generator circuit. The Schottky barrier diode employed is selected to have low internal resistance and uniformity of breakdown across the junction area.，下面是Schottky barrier diode noise generator专利的具体信息内容。
2. An electrical noise generator as defined in claim 1 wherein said Schottky barrier diode comprises a chip of semiconductor material, a layer of metal deposited over at least a portion of one surface of said chip thereby creating a Schottky barrier junction between said metal layer and said chip of semiconductive material, said Schottky barrier junction extending over a junction area sufficiently large to dissipate the DC power produced when said Schottky barrier diode is biased into the breakdown region.
3. An electrical noise generator as defined in claim 2 wherein said chip of semiconductive material comprises epitaxial silicon.
4. An electrical noise generator as defined in claim 1 wherein said Schottky barrier diode is housed in a case, said case comprising a metal base for mounting of said chip thereon to provide an efficient thermal transfer path for the heat generated in the diode.
5. An electrical noise generator as defined in claim 1 wherein said biasing means comprises a DC return path connected at one end to one of said diode electrodes and adaptable at the other end thereof to be connected to one terminal of a DC voltage source.
6. An electrical noise generator as defined in claim 5 wherein said DC return path comprises an inductor having one end thereof connected to said one electrode of said diode and the other end thereof adaptable to be connected to said one terminal of said DC voltage source.
7. An electrical noise generator as defined in claim 5 wherein said One electrode comprises the anode of said Schottky diode.
8. An electrical noise generator as defined in claim 6 including means for connecting the cathode of said Schottky diode to the positive terminal of a DC voltage source.
9. A noise generator as defined in claim 5 wherein said biasing means includes a capacitor connected between the other of said diode electrodes and said one terminal of said DC voltage source.
10. A noise generator as defined in claim 9 including a current limiting resistor connected at one end to the other of said diode electrodes and adaptable for connection at its other end to the other terminal of said DC voltage source.
