Latest Patent Applications

Jongmi Lee has filed several notable patent applications, including:

1. **QUADRATURE NOISE SHAPINGSAR ADC AND OPERATION METHOD THEREOF** - This application describes an analog-to-digital converter (ADC) that includes a first successive approximation register (SAR) ADC for converting an in-phase input signal to digital data using a first integrator. It also features a second SAR ADC for converting a quadrature input signal to digital data using a second integrator. The design incorporates first to fourth sampling capacitors that facilitate the integration of sampled input signals. The operation of the SAR ADCs and sampling capacitors is driven by a specific sequence of sampling, conversion, and integration stages.

2. **SAB BASED LOOP FILTER WITH CROSS-COUPLED STRUCTURE AND ADC INCLUDING THE SAME** - This application discloses a loop filter that comprises a first single-amplifier biquad (SAB) integrator for applying an integration operation to an in-phase input signal. It also includes a second SAB integrator for a quadrature input signal, along with cross-coupled paths that apply gains to the output voltages of the integrators.
