给出基于0.13μm CMOS工艺、采用单时钟动态负载锁存器设计的四分频器。该四分频器由两级二分频器级联而成,级间采用缓冲电路实现隔离和电平匹配。后仿真结果表明其最高工作频率达37 GHz,分频范围为27 GHz。当电源电压为1.2 V、工作频率为37 GHz时,其功耗小于30 mW,芯片面积为0.33×0.28 mm2。 A quarter frequency divider based on a 0.13μm CMOS process with a single clock dynamic load latch is given. The quad-band divider by two cascaded two, using buffer between levels to achieve isolation and level matching. Post-simulation results show that the maximum operating frequency of 37 GHz, frequency division range of 27 GHz. When the supply voltage is 1.2 V and the operating frequency is 37 GHz, the power consumption is less than 30 mW and the chip area is 0.33 × 0.28 mm2.
