提出了一种覆盖两个以上倍频程带宽的宽带互补金属氧化物半导体（CMOS）半动态三分频。通过采用三级 RC 多相滤波器实现无需正交信号源的宽带操作。对II型两级和三级多相滤波器进行传递函数分析，以提供峰值相位误差和峰值衰减的解析解。该除以 3 采用 0.18 µm CMOS 实现，可在 0.6 至 2.7 GHz 的输入频率范围内运行，同时从 1.8 V 电源消耗 15 mA 电流。
A wideband complementary metal oxide semiconductor (CMOS) semidynamic frequency divide-by-3 covering more than two octave bandwidths is presented. The wideband operation without requiring a quadrature signal source is realized by employing a three-stage RC polyphase filter. The transfer function analysis on Type-II two- and three-stage polyphase filters is performed to provide analytic solutions of the peak phase error and peak attenuation. Implemented in 0.18 mum CMOS, the divide-by-3 operates over the input frequency range between 0.6 and 2.7 GHz while dissipating 15 mA from a 1.8 V supply.
