摘要: A dynamic power adjustment circuit for noise rejection in a capacitance touch system includes: source configured to generate fixed voltage V, electrically connected the source, and detection circuit. The is plurality of different signals VH(1), VH(2), …, VH(n) from select one as an adjusting VH according selection signal VH_SEL, output level shift driving voltage. VH_SEL sensing RX generated by device system.
