Title:
ON-CHIP VARIABLE GAIN TEMPERATURE COMPENSATION AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2020/228456
Kind Code:
A1
Abstract:
An on-chip variable gain temperature compensation amplifier, which adjusts the proportion of positive gain and negative gain by altering a bias voltage of a gain control transistor at different temperatures, so as to implement gain control by means of positive and negative offsetting, and thus compensate for the influence of on-chip temperature changes on device gain. The temperature compensation amplifier covers temperature changes from -55°C to 125°C, and has advantages such as a large gain range, high compensation accuracy, low power consumption and a simple structure.
