This article presents a capacitance readout (CR) IC for both 2-D touch and 3-D proximity sensing. By employing hysteresis loop (HL) filtering and an external noise-monitoring schemes. the proposed CR IC solves reduced sensitivity in mutual-capacitance proximity sensing. Based on this HL filtering. https://www.bekindtopets.com/hot-mega-Swish-Supreme-Glide-Track-White-great-pick/
