DRIVING DEVICE FOR DYNAMIC BIAS AND DRIVING METHOD THEREOF
First Claim
1. A driving device for dynamic bias, comprising:
- a buffer, having an input terminal receiving a data voltage, and an output terminal coupled to a load through a switch; and
a bias control unit, connected to the buffer, for dynamically controlling a bias of the buffer, wherein the bias control unit controls the buffer to operate in a normal bias state during a transition period of the data voltage, the bias control unit controls the buffer to operate in a low bias state during a power-saving period, and controls the buffer to operate in the normal bias state during a transition period of switching the switch from a turned-on state to a turned-off state.

Abstract
A driving device and a driving method for dynamic bias are provided. The driving device includes a buffer and a bias control unit. An input terminal of the buffer receives a data voltage, and an output terminal of the buffer is connected to a load through a switch. The bias control unit connected to the buffer controls a bias of the buffer dynamically. During a transition period of the data voltage, the bias control unit controls the buffer in a normal bias state. During a power-saving period, the bias control unit controls the buffer in a low bias state, and controls the buffer in the normal bias state during a turning-off period of the switch. The driving device controls the buffer to sustain data voltage quickly during the turning-off period of the switch, so as to avoid the data voltage received by the load having errors and reduce power consumption.
