Abstract
A source driver and a receiver thereof are disclosed. A two-stage amplifier of the receiver includes a first-stage circuit and a second-stage circuit. The second-stage circuit includes a first switch, a second switch, a third switch, a first node, and a second node. The first switch is coupled between the first node and a ground end; the second switch is coupled between the second node and the ground end; the third switch is coupled between the first node and the second node. When the receiver wants to wake up from a power-saving mode to a normal operation mode, the first switch and the second switch are switched to the off-state according to a control signal at first; after a period of delay time, the third switch is also switched to the off-state according to a delayed control signal.
