Title: Hojin Park: Innovator in Touch Technology
Introduction
Hojin Park is a notable inventor based in Suwon-si, South Korea. He has made significant contributions to the field of touch technology, holding three patents to his name. His work primarily focuses on enhancing the functionality and efficiency of touch-sensitive devices.
Latest Patents
Hojin Park's latest patents include innovative designs for touch analog front ends and touch sensor controllers. One of his patents describes a touch analog front-end (AFE) for a touch-sensitive screen, which features a transmitter that charges the touch panel and a receiver that senses it. The receiver incorporates a charge-to-voltage (C2V) converter that transforms changes in capacitance from the touch panel into a voltage signal. Additionally, it includes a correlated double sampling (CDS) block that converts the voltage signal into a differential signal, sampling both positive and negative signals. An integrator is also part of the design, which accumulates the difference between the sampled signals. Another patent outlines a touch AFE and a touch sensor controller (TSC) that includes similar components, with added features such as a filter to eliminate noise from the voltage signal and a polarity detection circuit that manages the integrator's polarity based on the filtered voltage signal.
