摘要： A SSTL memory interface pre-driver stage that uses a voltage regulator to generate a ‘virtual’ ground reference voltage is provided. The ‘virtual’ ground voltage reference, being greater than a zero volt ground voltage, allows low voltage transistors to be used, thereby improving interface performance and decreasing system power consumption. The pre-driver stage uses a biasing circuit to bias the voltage regulator, formed by a transistor arranged in a source follower configuration, to generate the ‘virtual’ ground reference voltage off which a voltage translator stage of the pre-driver stage operates to generate an output of the pre-driver stage.

摘要： A SSTL memory interface pre-driver stage that uses a voltage regulator to generate a ‘virtual’ supply is provided. The ‘virtual’ supply, being lower than a power supply voltage of the pre-driver stage, allows low voltage transistors to be used, thereby improving interface performance and decreasing system power consumption. The pre-driver stage uses a biasing circuit to bias the voltage regulator, formed by a transistor arranged in a source follower configuration, to generate the ‘virtual’ supply off which a voltage translator stage of the pre-driver stage operates to generate an output of the pre-driver stage.
