Latest Patents
One of his latest inventions is an EMI noise shielding device. This device is designed to be applied to a power supply control system. It includes a first resistor that is electrically coupled to a second resistor, forming an input terminal. A differential amplifier receives a feedback voltage (Vfb) signal containing noise from the input terminal. This amplifier performs a first filter process to generate a first node voltage (VA) signal. A signal converter then receives the VA signal to perform an analog-to-digital conversion and a second filter process, resulting in a second node voltage (VB) signal. Finally, a digital control circuit processes the VB signal to filter out noise, ensuring the normal operation of the power supply control system.
Another significant invention by Tung is a digital pulse width modulation device. This device comprises a counter, a first comparator, and a second comparator. The first and second comparators are connected in parallel and in series with the counter. The counter sends a count signal to both comparators simultaneously, starting a count upon receiving a clock signal. The first comparator generates a pulse output corresponding to the pulse duty width signal. Meanwhile, the second comparator outputs a clear signal to reset the counter when the count reaches a specified total pulse duty length, thus correcting the output pulse.
