Latest Patents
Among her latest patents is an innovative analog-to-digital converter that features time-constant tuning with a pulse-width-based reference current and resistance searching. This sigma-delta analog-to-digital converter includes an initial continuous-time integration stage with a variable input resistor and an integration capacitor. A switched-capacitor circuit is employed to charge and discharge a replica capacitor to a reference voltage, generating a bias current. Additionally, a SAR-based tuning circuit incorporates a variable tuning resistor that produces a tuning voltage while conducting a mirrored version of the bias current. The resistance of the variable input resistor is adjusted in response to a tuning code from the SAR-based tuning circuit.
Another notable patent is for a pipelined analog-to-digital conversion apparatus. This apparatus includes a pipelined analog-to-digital converter (ADC) that consists of a first stage and a second stage. The first stage features a sampler and a quantizer connected to the sampler, along with a current distribution circuit. The second stage also includes a sampler linked to the current distribution circuit and a quantizer associated with the second stage's sampler.
