| Zusammenfassung: | A wide supply range digital level shifter circuit shifts between a variable desired output voltage ranging from a first voltage level and a second voltage level. The wide supply range digital level shifter circuit includes a latch circuit, a first bleeder circuit, and a second bleeder circuit. The latch circuit receives the first voltage level and the second voltage level, and includes first and second clocked differential switches. The first bleeder circuit is connected between the second voltage rail and the first differential switch and is configured to receive a first digital input voltage. The second bleeder circuit is connected between the second voltage rail and the second differential switch and is configured to receive a second digital input voltage. The first and second bleeder circuits isolate the first and second digital input voltages from the variable desired output voltage. |
