摘要：A mobile communication device compris a plurality of receivers, a pha detection circuit, and a DC offt calibration circuit. Each receiver compris a receiver chain and a divide-by-2 circuit that supplies Local Oscillating (LO) signal for the receiver chain. The LO signals leak to each receiver chain and create an undesirable DC offt
voltage. The DC offt depends on an LNA gain and a pha relation among the LO leakages. In a first novel aspect, a two-dimensional DC offt calibration (DCOC) table is prepared for each receiver chain. In a cond novel aspect, the pha detection circuit detects the pha relation among the LO leakages for each receiver chain. Bad on the LNA gain and the detected pha relation of each receiver chain, a DCOC code is lected from a corresponding DCOC table such that the calibration circuit calibrates the DC offt for each receiver effectively and efficiently.雷锋的主要事迹
