Document Type and Number:
WIPO Patent Application WO/2024/021651
Kind Code:
A1
Abstract:
An analog front-end chip (1) and an oscilloscope. An input buffer module (11), a variable gain amplification module (12), and at least two output branches (13) are integrated in the analog front-end chip (1). An input end of the input buffer module (11) serves as an input end of the analog front-end chip (1), and an output end of the input buffer module (11) is electrically connected to an input end of the variable gain amplification module (12). An input end of each output branch (13) is electrically connected to an output end of the variable gain amplification module (12), and an output end of each output branch (13) serves as an output end of the analog front-end chip (1). Each output branch (13) comprises an output buffer module (131).
