Reducing Parasitic Capacitance - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097619 titled 'Reducing Parasitic Capacitance
Simplified Explanation
The patent application describes an apparatus for reducing parasitic capacitance using a differential cascode configuration in an amplifier.
- The apparatus includes an amplifier with a first transistor operating as an input stage and a second transistor operating as a cascode stage.
- Both transistors have uniform doping types across their channel terminal regions.
- The first and second transistors have electrical contacts abutting their channel terminal regions, while the second transistor forms a floating region at a floating node.
- The number of electrical contacts abutting the channel terminal regions is greater than those abutting the surface of the floating region.
