Latest Patents

Choi's latest patents include innovative technologies that enhance the functionality and efficiency of electronic devices. One of his key inventions is a fuse circuit that can sense the state of a fuse that is programmed but not open. This technology allows for the application of a program current to the fuse, which increases its impedance without opening it. By maintaining essentially zero current through the fuse after programming, this invention ensures reduced current consumption and accurate sensing of the programming state. The fuse can be determined to be in a programmed or unprogrammed state, with low impedance in the unprogrammed state and high impedance in the programmed state.

Another significant patent is the mute control circuit, which simplifies the process of removing switching noise during the muting of outputs. This circuit reduces the number of connection pins required for integrated circuits. It includes a pulse generator, a charge/discharge signal generator, a controller, and a switching signal generator, all working together to efficiently manage the mute operation.
