A new proposed gate-bias voltage-generating technique with threshold-voltage compensation for analog circuits in the low-temperature polycrystalline silicon (LTPS) thin-film transistors (TFTs) is proposed. The new proposed gate-bias voltage-generating circuit with threshold-voltage compensation has been successfully verified in an 8-μm LTPS process. The experimental results have shown that the impact of TFT threshold-voltage variation on the biasing circuit can be reduced from 30% to 5% under a biasing voltage of 3 V. The new proposed gate-bias voltage-generating technique with threshold-voltage compensation enables the analog circuits to be integrated and implemented by the LTPS process on glass substrate for an active matrix LCD panel.
