Latest Patents
Nam's latest patents include a hybrid digital-to-analog converter non-linearity calibration system. This invention describes systems, apparatuses, and methods for performing hybrid non-linearity correction for a digital-to-analog converter (DAC). The circuit features two correction lookup tables (LUTs), an edge-trim DAC, and a DAC core. A lookup of the first correction LUT is performed using a portion of the most significant bits (MSBs) of a received digital input value. The first correction value, retrieved from the first correction LUT, is applied to the digital input value to generate a corrected value. This corrected value is then provided to the DAC core and to a second correction LUT. A second correction value, retrieved from the second correction LUT, is compared to the first correction value. If the second correction value differs from the first, the difference is sent to the edge-trim DAC to generate an analog correction applied to the DAC core's analog output.
Another significant patent by Nam is a multi-stage overload protection scheme for pipeline analog-to-digital converters. This apparatus includes a series of ADC stages and a comparison circuit linked to the first ADC stage. The first ADC stage is designed to compare an input signal to one or more conversion thresholds to generate a result. It can also produce an output signal based on the result's value. Upon receiving a reset signal, the first ADC stage sets the output signal voltage to a specific level. The comparison circuit asserts the reset signal when the input signal voltage exceeds the defined operating range.
