Latest Patents

One of Tie Jun Dai's latest patents is focused on "Missing code redistribution in pipeline analog to digital converter." This invention involves a stage of a pipeline analog to digital converter (ADC) that includes a multiplying digital to analog converter (MDAC) and a sub-analog to digital converter (sub-ADC). The sub-ADC features a comparator that compares a first analog signal with a reference signal, while a random offset controller applies a random offset to distribute errors in the digital output of the pipeline ADC.

Another notable patent is the "Zero DC current readout circuit for CMOS image sensor using a discharge capacitor." This method outlines a process for reading out a light signal from a pixel. It involves charging a capacitor to a predetermined voltage during a precharge stage and then discharging it through a pixel output transistor during the readout stage. The output signal is determined by the voltage held by the capacitor, modulated by the light signal.
