Abstract

An on-panel delta-sigma analog-to-digital converter (ADC) has been implemented and verified for 3-μm low-temperature polysilicon (LTPS) technology with two basic blocks: a delta-sigma modulator and a decimation filter. From the experimental results, the digital output from the delta-sigma modulator is correctly matched with the analog input voltage ratio such that the digital output can be converted into 8-bit digital code successfully under a supply voltage of 10 V from the decimation filter. The implemented on-panel delta-sigma ADC can be used for the application of temperature-to-digital converter on glass substrate.
