Latest Patents

Adam Wu holds a patent for a "Test circuit and method of trimming a unary digital-to-analog converter." This invention focuses on improving the accuracy of unary digital-to-analog converters in subranging ADCs. The method involves toggling an offset cell at the input to the coarse quantizer and a reference cell in the DAC. This process allows for the last least significant bit (LSB) of the reconstructed signal to be accurately measured. The test circuit measures the output voltage of the summing amplifier under different conditions and generates an error voltage, effectively rejecting common mode terms. The cell under test is then laser trimmed to minimize the error voltage until the differential non-linearity (DNL) error is within a specified tolerance. This innovative approach also includes a dithered tolerance to enhance the spur-free dynamic range.
