In this paper, a voltage regulator which can be integrated on a LCD panel using LTPS-TFT is proposed. The new voltage regulator can be reduced the deviation rate of the reference voltage (α') depending on the load fluctuation because the new voltage regulator provides a reference voltage shifter (RVS).
By utilizing this circuit configulation, the proposed regulator can be obtained a stable constant output voltage. To confirm some performances of the proposed voltage regulator, the circuit analysis is carried out by using Smart-SPICE. As this results, the regulation rate of the output voltage (α) of the proposed voltage regulator is improved about 50% in comparison with that of conventional circuit under the conditions that the supply voltage (VDD) is +15V, the frequency (f) with the load current of+0.5㎃±0.5㎃ is 250㎑.
