With a total of three patents to his name, Duan has made significant strides in enhancing the performance and reliability of electronic circuits.

Latest Patents

One of Duan's latest patents is the "Traveling-wave transimpedance amplifier." This innovative design features a distributed amplifier that utilizes multiple transistors to receive a propagating input signal. The transistors drive corresponding nodes of an amplified signal line, which propagates an amplified signal to an output voltage buffer. The feedback impedance couples the output voltage to a feedback node, ensuring that the output voltage is proportional to the input signal's current. The method involves propagating an input signal current along the input signal line and buffering the amplified signal to produce an output voltage signal.

Another notable patent is the "Adaptive control of meta-stability error bias in asynchronous successive approximation register ADC." This invention addresses the statistical effects of meta-stability induced errors in successive approximation register analog-to-digital converters (SAR ADCs). The integrated circuit chip includes a SAR ADC that employs asynchronous bit cycles to convert analog signal samples into digital signal samples. A detector accelerates the asynchronous bit cycles when a meta-stability error bias exceeds a predetermined threshold, enhancing the reliability of the conversion process.
