Latest Patents

One of his latest patents is an analog-to-digital converter (ADC) that features a coarse ADC. This device receives an analog input voltage and generates a first digital signal using a successive approximation register (SAR) method. It also outputs a residual voltage remaining after the first digital signal is generated. The ADC includes an amplifier that receives the residual voltage and a test voltage, generating a residual current by amplifying the residual voltage by a predetermined gain. Additionally, it generates a test current by amplifying the test voltage by the same gain. The fine ADC then receives the residual current and generates a second digital signal based on this current using the SAR method. An auxiliary path receives the test current and generates a gain correction signal based on it, allowing the amplifier's gain to be adjusted accordingly.

Another notable patent involves an analog-to-digital converter that consists of a voltage-current converter. This converter receives an analog input voltage, generates a first digital signal from it, and outputs a residual current remaining after the first digital signal. A current-time converter then converts the residual current into a current time in the time domain. Finally, a time-digital converter receives the residual time and generates a second digital signal from it. Both digital signals represent the respective signal levels of the analog input voltage.
