High output power low temperature polysilicon thin-film transistor boost converters for large-area sensor and actuator applications
Source abstract
Abstract
Abstract Large-area electronic sensor and actuator arrays are suitable systems for thin-film transistor (TFT) technology with numerous applications from consumer electronics to healthcare. Considerable effort is being spent to make these arrays a reality. However, research on the power delivery circuits that supply these arrays has remained largely unexplored. This work delves into the design trade-offs and characterization of high output power boost converters in low-temperature polysilicon (LTPS) technology. The proposed boost converters deliver 0.62–2.17 W of output power, orders of magnitude above prior TFT solutions, with efficiencies ranging from 47 to 69.5%. These boost converters enable the realization of large-area sensor and actuator arrays and set the foundation for future research in this area.
