In this paper, the importance and perspective for the digitally-assisted analog and RF circuits are discussed, especially related to wireless transceivers. Digital calibration techniques for compensating I/Q mismatch, IM2, and LO impairments in cellular, 2.4 GHz WiFi, and 60 GHz WiGig transceivers are introduced with detailed analysis and circuit implementations. Future technology directions such as the shift from digitally-assisted analog circuit to digitally-designed analog circuit will also be discussed.
