Multi-modulus frequency divider and electronic apparatus including the same

An electronic apparatus comprising:

• a multi-modulus frequency divider and at least one electronic component connected to the multi-modulus frequency divider, wherein the multi-modulus frequency divider comprises:
• a frequency division module, a frequency selection module, and a retiming module,
• wherein the frequency division module is configured to receive an input signal and perform multi-mode frequency processing on the input signal, so as to generate and output a plurality of divided signals to the frequency selection module,
• wherein the frequency selection module is configured to receive the plurality of divided signals from the frequency division module, select a divided signal having a desired frequency from among the plurality of divided signals, and output the selected divided signal to the retiming module,
• wherein the retiming module is configured to receive the selected divided signal from the frequency selection module, perform a retiming operation on the selected divided signal, and output a retimed selected divided signal,
• wherein the frequency division module comprises N number of differential cascading frequency divider cells connected in stages and configured to divide by 2 or by 3, the frequency divider cells include complementary metal-oxide-semiconductor (CMOS) logic-based high-speed differential D flip-flops, and N is an integer greater than or equal to 2, each frequency divider cell has a control input terminal and a mode stop (MS) input terminal, wherein the control input terminal accepts a combinational logic signal, the mode stop (MS) input terminal accepts a mode stop (MS) signal that is generated from the combinational logic signal, and wherein the mode stop (MS) signal turns off the corresponding frequency divider cell after the first stage.
