摘要： An analog-to-digital converter (ADC) and a receiver that includes the ADC is disclosed. The ADC includes a first filter configured to receive a signal in an I-signal path of the receiver and a second filter configured to receive a signal in a Q-signal path of the receiver. The ADC further includes a quantizer alternatingly in connection with the first and second filters, and at least one DAC alternatingly in connection with the first and second filters. Switches in the ADC are configured to alternate connection between an input of the quantizer and outputs of the first and second filters, and are also configured to alternate connection between an output of the at least one DAC and inputs of the first and second filters.
