Abstract
A touch detection circuit is provided, including an analog-to-digital conversion circuit configured to receive an analog touch signal output by touch electrodes and convert the analog touch signal into a digital touch signal; a spectrum extraction circuit electrically connected to the analog-to-digital conversion circuit and configured to obtain a component signal corresponding to at least one preset frequency of the digital touch signal within a preset time interval; an amplitude and phase extraction circuit electrically connected to the spectrum extraction circuit and configured to obtain an amplitude of the component signal, the touch detection circuit determines a touch position of the touch electrodes according to the amplitude of the component signal. A touch device is further provided. Thereby, the touch detection circuit and touch device provided by the present application can reduce the bus bandwidth required for data transmission and lower the power consumption of the processor.
