LATCH AND FREQUENCY DIVIDER |
| 摘要 |
A latch and a frequency divider are provided. The latch includes: a first logic unit coupled between a power supply and a ground wire, wherein the first logic unit comprises a first control terminal, a first input terminal and a first output terminal; a second logic unit having a structure symmetrical to that of the first logic unit, wherein the second logic unit comprises a second control terminal, a second input terminal and a second output terminal; and a feedforward control unit adapted for cutting off a current path in the first logic unit or the second logic unit based on signals inputted into the first input terminal and the second input terminal. Power consumption of the latch can be reduced in both static working condition and dynamic working condition. |
