With a total of 3 patents to his name, Kim's work has had a substantial impact on the efficiency and functionality of electronic devices.
Latest Patents
One of Kim's latest patents is titled "Method and apparatus for voltage compensation for parasitic impedance." This invention provides an apparatus and method for regulating voltage to a load, compensating for parasitic impedances. The design includes a first amplifier that measures the voltage drop due to a first parasitic impedance, and a second amplifier that measures the voltage drop due to a second parasitic impedance. An offset generator sums these voltage drops with a reference voltage, driving a DC-to-DC converter to produce an input voltage that matches the summed voltages. This innovation ensures that the voltage at a load, such as a computer microprocessor, aligns with the reference voltage.
Another significant patent by Kim is the "Method and apparatus for monitoring discharge of a battery device." This novel battery monitoring device determines the amount of battery self-discharge and the discharge from a monitoring circuit. It also assesses battery discharge from a host device in two different power consumption modes. The first mode results in greater battery discharge over a given period compared to the second mode, enhancing the understanding of battery performance in various operational states.
