Latest Patents
Benrud's latest patents reflect his innovative prowess:
1. **Low Input Capacitance Amplifier** - This invention features a first feedback loop to a regulator transistor within the drain circuit of the input field effect transistor (FET). It is designed to maintain a constant voltage across the drain-gate junction of the input FET, which helps reduce junction-to-junction capacitances. The amplifier includes additional feedback loops that create guard circuits, further mitigating capacitance issues. When compacted for microprobing of low voltage nanosecond rise time signals, this amplifier achieves an impressive effective input capacitance of less than 0.5 picofarads.
2. **Differential Magneto-Resistive Detector for Cross-Tie Wall Memory System** - This patent outlines a method and apparatus for detecting information magneto-resistively in a cross-tie memory system. It includes a series of conductive elements aligned along a magnetic, serrated-edged data track, with two gaps positioned at respective narrow portions. A differential sense amplifier is utilized across these gaps to discern the presence of a cross-tie, showcasing the invention's potential in memory technology.
