Voltage level shifter and display device |
摘要 |
A voltage level shifter comprises an input stage in the form of cross-coupled source followers and an output stage in the form of an amplifier AMP, which may have single-ended or differential inputs. The source followers comprise the transistors M1 and M2 and the transistors M3 and M4. Differential inputs IN and !IN are connected to the gates of the transistors M2 and M4. A bias voltage is supplied to the gate of the transistor M1 from a node B to which the drain of the transistor M3 and the source of the transistor M4 are connected. Similarly, a bias voltage is supplied to the gate of the transistor M3 from a node A to which the drain of the transistor M1 and the source of the transistor M2 are connected.
