LEVEL SHIFTING CIRCUIT FOR HIGH VOLTAGE APPLICATIONS |
摘要 |
A level shifting circuit includes a current mirror that generates a first bias current and a second bias current (proportional to the first bias current with a first ratio). A first level shifter is coupled between a first input node (receiving a first input signal) and a first output node coupled to an input of the current mirror. The first level shifter applies a first voltage variation to the first input signal in response to the first bias current. A second level is coupled between a second input node (receiving a second input signal) and a second output node coupled to an output of the current mirror. The second level shifter applies a second voltage variation (associated with the first voltage variation) to the second input signal in response to the second bias current. |
