Abstract:
1. A dual path level shifter comprising: a dual path level shifter input terminal; a dual path level shifter output terminal; a first voltage-to-current converter; a second voltage-to-current converter; a third voltage-to-current converter; a first current-to-voltage converter; and a second current-to-voltage converter, wherein: in a first condition, during operation, an input signal having an input signal level is routed from the dual path level shifter input terminal to the first voltage-to-current-converter, from the first voltage-to-current-converter to the second current-to-voltage-converter, from the second current-to-voltage converter to the third voltage-to-current converter, from the third voltage-to current-converter to the first current-to-voltage converter and from the first current-to-voltage converter to the dual path level shifter output terminal; and in a second condition, during operation, the input signal is routed from the dual path level shifter input terminal to the second voltage-to-current converter, from the second voltage-to-current converter to the first current-to-voltage converter and from the first current-to-voltage converter to the dual path level shifter output terminal, whereby the input signal level is shifted to an output signal level.
