Abstract
Provided is a signal driving system with a constant slew. The signal driving system with the constant slew includes: a step voltage generation unit configured to provide multiplex arithmetic gradient voltage signals; a multiplexer, wherein an input end of the multiplexer is connected to the step voltage generation unit to receive the multiplex arithmetic gradient voltage signals, and another input end of the multiplexer is connected to a control signal generation unit, and the multiplexer is configured to selectively output the multiplex arithmetic gradient voltage signals under a control of a control signal generated by the control signal generation unit; a voltage following unit connected to the multiplexer, wherein the voltage following unit is configured to serve as an isolation and improve a driving ability; and an output following unit connected to the voltage following unit, wherein the output following unit is configured to drive a subsequently-connected load unit.
