  • Buffer amplifier for ripple-carry binary generator
    Patent number: 3956640
    Abstract: A buffer amplifier for use with a ripple-carry binary generator comprises a pair of serially connected FET transistors. The input to one of the transistors is precharged by the preceding generator stage and also receives the ripple carry signal. A feedback loop from the output of the transistor to the input hastens the transition from the pre-charge condition to ground.

  • Amplifier for random access computer memory
    Patent number: 3950709
    Abstract: An integrated circuit ram amplifier includes a feedback loop which produces an output pulse before the output from the random access memory has completed its transition from full voltage to ground, thus increasing the computer's response time. The integrated circuit amplifier may find particular application in microprocessors (e.g. 8 bit word length, single bus two phase clock microprocessors).
