Abstract: Leakage reduction plays an important role in power consumption in many of the systems like image sensors. Adaptive bulk biasing control scheme is used to reduce the leakage during the standby mode of operation in the systems. Advanced WDR image sensors used to take images especially in situations where the light enters a premise from different angles, i.e. where both the dark and bright areas are there in the camera field of view that provides continuous tone images. Every pixel is to be converted in to halftone pixels in any of the conventional press, in order to print the image. Here a halftone pixel is generated using Floyd-Steinberg algorithm. The adaptive bulk biasing control scheme provides 21% power reduction as compared to any other standard systems.
