Transceiver and method for converting signals of the transceiver thereof

Abstract

The invention provides a transceiver and a method for converting signals of the transceiver thereof, wherein the transceiver includes an analog-to-digital converter (ADC) for converting an analog input signal into a digital output signal during a first operational phase of the transceiver, and converting the digital output signal into the analog input signal during a second operational phase of the transceiver. The ADC includes: an embedded processing circuit and an embedded digital-to-analog converting (DAC) unit, wherein the embedded processing circuit is arranged to generate a digital code and digital output signals according to the analog input signal and an analog signal in the first operational phase of the transceiver; the DAC unit is coupled to the embedded processing circuit, the embedded DAC unit is arranged to convert the digital code into the analog signal during the first operational phase, and is arranged to convert a digital input signal into an analog output signal during a second operational phase of the transceiver. One of the advantages of the invention is saving the layout area and decreasing the hardware manufacturing cost under the premise of realizing the transceiving function.

Description

technical field [0001] The present invention relates to related technologies of transceivers, and more particularly, relates to at least one transceiver and a signal conversion method thereof. Background technique [0002] In traditional baseband analog-to-digital conversion (Analog-to-Digital Conversion, ADC) / digital-to-analog conversion (Digital-to-Analog Conversion, DAC) architecture, a separate (individual) ADC (usually called RXADC) and the DAC used for the transmit phase (often called TXDAC). In a Time-Domain Duplex (TDD) system, since the uplink (uplink) and downlink (downlink) of communication are separated from each other, the RXADC and TXDAC of the ADC / DAC architecture do not need to operate at the same time. [0003] figure 1 is a schematic diagram of a conventional transceiver 100 . Conventional transceiver 100 includes RXADC 110 and TXDAC 120 . The RXADC 110 here is used to convert the analog input signal S AIN converted to a digital output signal S DOUT...

Problems solved by technology

[0004] However, the DAC unit usually occupies a large layout area; in addition, when the traditional transceiver 100 is applied in a TDD system, the DAC unit of the RXADC 110 and the DAC unit of the TXDAC 120 do not need to operate at the same time, therefore, when transmitting signals or receiving signal when one of the above two DAC units is idle
