VOLTAGE LEVEL SHIFTER, DECOUPLER FOR A VOLTAGE LEVEL SHIFTER, AND VOLTAGE SHIFTING METHOD |
摘要 |
A voltage level shifter for translating a binary input signal representing a binary sequence to a binary output signal representing the same binary sequence. The voltage level shifter comprises an input port for receiving the binary input signal as an input voltage varying between a first input voltage level and a second input voltage level. An output port is connected to a node for outputting the binary output signal as an output voltage varying between a first output voltage level and a second output voltage level. A supply voltage node connectable to a voltage supply, can provide the second output voltage level. A first switch is arranged to couple the supply voltage node to the node and to decouple the supply voltage node from the node based on a voltage at the node. A feedback voltage loop is connected to the node for providing a feedback voltage based on the voltage at the node. A second switch is connected to the feedback voltage loop and arranged to couple the input port to the node based on a voltage at the input port and the feedback voltage. A decoupler and a voltage shifting method are also disclosed.
