The apparatus includes a pulse modulator configured to output a charging signal including at least one pulse. A switch is configured to charge the capacitive sensor according to the charging signal and output a discharging signal from the capacitive sensor. A discharging compensator is configured to output a discharging delay signal by compensating a voltage level of the discharging signal during a falling period of the discharging signal. A detector is configured to output a detection signal by detecting a region where the discharging delay signal has a voltage threshold. A controller is configured to detect the capacitance change by measuring a discharging time of the capacitive sensor according to the detection signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus of detecting capacitance","description":"An apparatus of detecting capacitance detects a capacitance change of a capacitive sensor.
