摘要:
According to the present invention, after a bias circuit (20) starts, a startup circuit (10) is isolated from the bias circuit (20) according to a bias voltage generated on an isolating voltage node (V2) from the bias circuit (20) to the startup circuit (10), and steady current consumption can be prevented in the startup circuit (10).
