Latest Patents

Yen S Yee's latest patents include a Sequential Successive Approximation Analog-to-Digital Converter. This innovative pipelined analog-to-digital (A/D) conversion system enhances the effective data rate of the converter in direct proportion to the number of stages in the pipeline. The pipelined A/D converter operates in conjunction with a charge-coupled device (CCD) multilevel storage (MLS) in a three-bit (eight-level) implementation. Three comparators are utilized in the three-bit system, arranged in a sequential successive approximation configuration with control circuits and a CCD shift register.

Another notable patent is the Multi-Level Charge-Coupled Device Memory System. This invention describes a digital-to-analog conversion (DAC) circuit and trigger comparator combination for encoding and decoding charge packets in a common-well multi-level signal charge-coupled memory device (CCD). The DAC circuit, which may be of the weighted capacitor type, generates a staircase waveform and creates the common-well under a first gate in the CCD. The trigger comparator, adjacent to a second gate in the CCD, is a detection circuit that remains in one binary state until an input charge signal is received, at which point it switches state. The weighted capacitor DAC contains an extra offset bit used in the analog-to-digital or regeneration operation, ensuring that when the trigger comparator switches state, the digital input to the DAC accurately represents the signal charge being converted.
