Patent number: 8681840Abstract: A transceiver includes a transmitter circuit, a receiver circuit, and the loopback switch. The transmitter circuit performs a digital-to-analog conversion (DAC) operation on a calibration code without a transmission digital signal in a calibration mode to generate a calibration signal. The transmitter circuit up-converts the calibration signal and generates a transmission signal. The receiver circuit down-converts the transmission signal in the calibration mode and generates a receiving digital signal. The loopback switch electrically connects an output terminal of the transmitter circuit and an input terminal of the receiver circuit in the calibration mode. Thus, the transceiver may stably reduce a carrier leakage irrespective of processes, voltages, and temperatures.Type: GrantFiled: April 4, 2012Date of Patent: March 25, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Byoung-Joong Kang, Sung-Gi Yang, Joung-Hyun Yim
