Latest Patents

John M Beall holds a patent for a "Lateral varactor with staggered punch-through and method of fabrication." This invention involves a lateral varactor that is designed with a recess structure, which provides staggered punch-through points. This design allows the varactor to be tuned through punch-through without introducing significant non-linearities in either capacitance or Q. The lateral varactor includes a cathode and an anode positioned on the surface of an active layer. The unique structure of the anode, which consists of both a surface section and a recess section, results in a greater active layer depth under the anode surface section than under the recess section. Consequently, as the reverse-bias voltage on the anode increases, the depletion region reaches punch-through under the recess section before it does under the surface section. This design minimizes abrupt impedance changes during tuning, making the varactor tuning process more continuous.
