  • CMOS sense amplifier with level shifter
    Patent number: 4618785
    Abstract: A common mode gain enhancing CMOS differential sense amplifier for a static RAM memory, straddled by level shifting circuits during the respective differential inputs to the sense amplifier.
    Type: Grant
    Filed: September 6, 1984
    Date of Patent: October 21, 1986
    Assignee: Thomson Components - Mostek Corporation
    Inventor: Hiep van Tran
  • Power supply dependent voltage reference circuit
    Patent number: 4604732
    Abstract: A circuit adapted for use in comparing voltages in a manner that is insensitive to power supply variations includes a pair of reference cells controlling the reference voltage of a sense amplifier through control of a pair of reference transistors and an input circuit for conditioning data having a matched input pair of transistors, so that input data will control the voltage on the input terminal of a sense amplifier in a manner such that both inputs to the sense amp track voltage, thermal and processing variations.

  • CMOS Differential amplifier
    Patent number: 4567389
    Abstract: A differential sense amplifier employs a central region having two current paths each having a P- and N-type transistor in series, all four transistors having a common gate connection. Each input transistor has its source connected to the top of one current path and its drain connected to the bottom of the other current path, to apply the maximum differential input.
