Abstract:
1. A data signal generator, comprising: a controller for selectively generating one of a first control signal and a second control signal according to a bit value of data supplied to the controller; a voltage generator for generating a plurality of voltages, the voltage generator including a plurality of resistors disposed between a first voltage and a second voltage, the voltage generator including a plurality of nodes, each of the nodes disposed between two of the resistors and supplying one of the plurality of the voltages; a plurality of first switches, a voltage from one of the nodes being supplied to an output terminal through one of the first switches whenever the one of the first switches is turned on; a plurality of second switches coupled to the controller, the one of the first control signal and the second control signal being supplied to one of the first switches through one of the second switches whenever the one of the second switches is turned on, the one of the first switches being tuned on or off whenever the one of the first control signal and the second control signal is supplied to the one of the first switches; a plurality of capacitors, each of the capacitors coupled to a corresponding one of the second switches, the each of the capacitors being charged with the one of the first control signal and the second control signal supplied through the corresponding one of the second switches, the one of the first control signal and the second control signal stored in the each of the capacitors being supplied to one of the first switches that is coupled to the corresponding one of the second switches; and a plurality of shift registers, each of the shift registers coupled to one of the second switches, each of the shift registers supplying one of a reset signal and a shift signal to the one of the second switches.
