Latest Patents

Among his latest patents, Cho has developed a class D amplifier and a method of pulse width modulation. This innovative class D amplifier includes a sigma delta modulator, a reference signal generator, a pulse width modulator, and an amplifier. The sigma delta modulator converts an M bit input signal into N bit pulse code modulation data, where M is greater than N. The reference signal generator counts a system clock and generates an N bit reference signal with two data blocks in a sampling period of the pulse code modulation data. The pulse width modulator generates multiple pulse width modulation signals with at least two switching periods within the sampling period, varying the pulse widths based on a unit time interval of the reference signal.

Another significant patent involves a class-D power amplifier designed to eliminate excessive response phenomena when returning to a steady state from an abnormal state. This amplifier prevents saturation of integral control circuits by utilizing sub-negative feedback loop operations, thereby suppressing pop noise and reducing power consumption during transitions.
