Abstract
A current detection circuit comprises a signal input terminal, a signal output terminal, a switch branch, a first current detection branch, and a second current detection branch. The switch branch is configured to block the current flowing from the signal output terminal to the signal input terminal when the switch branch is turned off. When the switch branch is conducting, the current flowing from the signal input terminal through the switch branch to the signal output terminal is the switch branch current comprising a first part linearly related to a first voltage difference, and a second part exponentially related to the first voltage difference. The first voltage difference is the voltage difference between the signal input terminal and the signal output terminal. The first current detection branch outputs a first detection current representing the first part. The second current detection branch outputs a second detection current representing the second part.
