Latest Patents
SanHwa Chee holds a patent for a "Clock generator with comparator error compensation." This invention includes an amplifier that develops an error voltage based on the difference between a sample voltage of a charge voltage and a predetermined reference voltage. The charge voltage generates a clock signal, such as a sawtooth waveform. A comparator is utilized to compare the charge voltage with the error voltage, resulting in the development of a compare signal. The sample and discharge control network generates the sample voltage in response to the compare signal, facilitating the switching between charging and discharging of the charge voltage. The amplifier ensures that the charge voltage switches at the reference voltage level, effectively eliminating comparator errors, such as switching delay or input offset voltage. Additionally, a second comparator and another amplifier may be included to control switching in both directions, allowing for the development of a triangular waveform.
