This invention discloses a negative voltage effective transmission circuit on a standard logic technology including: a clock circuit outputting high level and low level clock signals alternately, a low voltage output channel outputting low voltages, the input of which is connected with said clock circuit output, when the clock signal output by the clock circuit is turned to low level from the high one, the low voltage output channel conduction is triggered to output the low voltage, a negative voltage output channel, the input of which is connected with the output of said clock circuit and the output of which is connected with the output of a zero voltage output channel as the output of the whole circuit, when the clock signal output by the clock circuit is turned to high level from the low, charges stored in a transistor playing the role of a couple condenser triggers the transmission gate conduction of said negative voltage output channel to output negative voltage. |
