In this paper, a modified voltage reference circuitry using LTPS TFT is proposed. The new modified voltage reference circuitry is unaffected by fluctuations of the power supply voltage and the ambient temperature due to the utilization of enhancement-depletion (E-D) reference circuit and the operation in the weak inversion region for generation of a stable reference voltage. To verify the performance of the new modified circuitry, the circuit simulation is carried out by using SPICE. As a result of the simulation, the supply voltage dependability (SVD) and the temperature coefficient (TC) achieves to values of 0.08967 [%/V] and 0.00203[%/℃], respectively, when the ambient temperature (Ta) is +25℃ and the supply voltage (VDD) is +8V. In brief, these characterisitcs of the new modified circuitry are improved comparing with that of the conventional circuit.
