The first AFE channel includes a first integrator having an input terminal coupled to the first terminal receiving a first sensing signal. The second AFE channel includes an input amplifier. The second AFE channel is coupled between the input terminal of the first integrator in the first AFE channel and a second terminal connected to the touch panel. The second AFE channel is configured to generate a reversal input signal based on a second sensing signal received by the second terminal and couple the reversal input signal to a common node between the first integrator and the first terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Analog front end circuit with noise cancellation","description":"The disclosure includes a touch display apparatus having AFE circuit that performs a noise cancellation of an AFE channel by utilizing noise signal received by a neighboring AFE channels.
