Latest Patents

One of Chung-woul Kim's latest patents is the "Ultra-low power limiter," which is an over-voltage protection circuit. This circuit includes a first switching block with multiple semiconductor elements that are connected in series and activated sequentially based on the input voltage magnitude. Additionally, it features several second switching blocks, each containing a pair of serially connected semiconductor elements with varying current properties. This design minimizes leakage current when the input voltage is below a reference voltage and maximizes it when above, ensuring that excessive current does not flow into the RF tag circuit while providing sufficient current to a regulator.

Another significant patent is the "Reference voltage generating circuit with ultra-low power consumption." This circuit comprises a constant current circuit that generates a first constant current from a supply voltage, a current mirror circuit that supplies a second constant current, and a voltage control circuit that produces a first reference voltage using substrate transistors driven by a PTAT voltage. The output circuit amplifies the output voltage to generate multiple reference voltages, maintaining stability despite variations in supply voltage, process, temperature, and other factors.
