摘要： One embodiment of the present invention provides a quadrature-mixing transmitter for wireless communication. The transmitter includes a quadrature modulator comprising an in-phase (I) channel and a quadrature (Q) channel, a calibration-signal generator configured to generate calibration signals that are sent to the I channel and the Q channel, and a calibration circuit configured to calibrate an imbalance between the I channel and the Q channel. The modulator, the calibration-signal generator, and the calibration circuit are located on a same integrated circuit (IC) chip, thereby facilitating on-chip calibration of the imbalance between the I channel and the Q channel.

摘要： One embodiment of the present invention provides a receiver for wireless communication. The receiver includes a demodulator and at least one filtering mechanism coupled to the demodulator, and an analog-to-digital converter (ADC) coupled to the filtering mechanism. The filtering mechanism can be configured to function as a low-pass filter (LPF) or a band-pass filter (BPF), thereby enabling the receiver to function as a direct-conversion receiver or a low-intermediate frequency (low-IF) receiver.
