A delta-sigma analog-to-digital (A/D) converter designed and implemented with the thin-film transistors (TFTs) on glass substrate is proposed, which has been successfully verified in a 3-μm low-temperature polycrystalline silicon (LTPS) process. The experimental results have shown that the probability in the bit stream of the digital output from the delta-sigma modulator is correctly fit in the analog input voltage ratio. Such a bit stream can be converted into 8-bit digital code successfully under the operation voltage of 10V with thin-film transistors (TFTs) on the glass substrate. The proposed delta-sigma A/D converter can be further used to achieve the precise analog circuits for System-on-Panel (SOP) or System-on-Glass (SOG) applications, which enables the analog circuits to be integrated in the active matrix LCD (AMLCD) panels.
