Variable drive current driver circuit |
摘要 |
Disclosed is a variable drive current driver circuit, comprising: a pair of push-pull circuits for driving a load circuit complementarily; a first current source circuit for having a bias current flow into the pair of push-pull circuits; a second current source circuit for having the bias current flow out of the pair of push-pull circuits; and a control circuit for varying both the bias current flowed by the first current source circuit and the bias current flowed by the second current source circuit according to a control signal.
