Abstract

A cell sampling circuit includes a plurality of target units sequentially connected in a series connection in a daisy-chain communication manner and one or more transformer units each connected between two successive target units of the plurality of target units. Each of the target units is configured to acquire an impedance of at least one transformer unit connected to the target unit, and judge, based on the acquired impedance, whether to perform circuit abnormality early warning.
