CMOS LEVEL SHIFT CIRCUIT WITH ACTIVE PULL-UP AND PULL-DOWN |
摘要 |
A CMOS level shift circuit with active pull-up uses a pair of pull up transistors activated during the period when an output node needs to be rapidly pulled up. The pull up transistors are activated by the outputs of a combinatorial logic or memory circuit detecting when a change of input signal has occurred and activating the respective pull up transistor to bring the output to the proper state. |
