Latest Patents

One of Yung-Ming Lee's latest patents is an amplifying circuit capable of suppressing spikes of an audio signal. This circuit includes an integration module, a comparison module, an output module, a feedback module, and a limiting module. The integration module receives an input signal and generates a first voltage signal corresponding to that input. The comparison module generates a comparison signal by receiving the first voltage signal and a reference signal. The output module then generates an audio signal based on the comparison signal. The feedback module feeds back an output signal to the integration module, while the limiting module ensures that the comparison signal remains within a predetermined range.

Another notable patent is a class-D power amplifier capable of reducing electromagnetic interference, which includes an integrator, a triangular wave generator, a comparator, a gate driver, a feedback circuit, and an output stage circuit. The integrator receives an input signal and outputs a first voltage. The comparator compares this first voltage with a triangular wave generated by the triangular wave generator to produce a pulse-width modulation signal. The gate driver then drives the output stage circuit to output an output voltage according to the pulse-width modulation signal, effectively reducing electromagnetic interference.
