Abstract: A mutual-capacitance detection circuit and a mutual-capacitance detection array are provided. The mutual-capacitance detection circuit comprises: a first capacitor; a limited current transmitting module, connected with an input end of the first capacitor and configured to control the first capacitor to output a current signal having an alternate positive and negative amplitude; and a receiving module, connected with an output end of the first capacitor and configured to output a digital level pulse signal according to the amplitude of the current signal output from the first capacitor, in which a width of the digital level pulse signal is positively related with the amplitude of the current signal output from the first capacitor.
