Abstract

In this paper, a CMOS digitized wind transducer with noise insensitivity for flowers in greenhouse applications is proposed. Based upon the device parameters of 0.35 μm 2P4M CMOS technology with 3.0 V power supply, all the functions and performance of the proposed digitized wind transducer are successfully tested and proven through measurements. The range of measured wind speed is tested from 2.2 to 8 m/s, and its corresponding SNDR is 53.6 to 74.6 dB. The chip area is 1.2 × 2.2 mm². The proposed general-purpose chip is suitable for various wind environmental monitoring applications, such as flowers in greenhouse.
