  • Cascode amplifier circuit for generating and maintaining a fast, stable and accurate bit line voltage
    Patent number: 6885250
    Abstract: A cascode amplifier circuit which generates a fast, stable and accurate bit line voltage is disclosed. According to one exemplary embodiment, the cascode amplifier circuit comprises a transistor having a source connected to a bit line voltage and a drain connected to an output voltage. The cascode amplifier circuit also comprises a differential circuit having an inverting input connected to the bit line voltage, a non-inverting input connected to a reference voltage, and an output connected to a gate of the first transistor. The operation of the transistor and the differential circuit generate a fast, stable the accurate bit line voltage.
