CASCODE AMPLIFIER CIRCUIT FOR PRODUCING A FAST, STABLE AND ACCURATE BIT LINE VOLTAGE

摘要

A cascode amplifier circuit (205), which generates a fast, stable and accurate bit line voltage (230), is disclosed. According to one exemplary embodiment, the cascode amplifier circuit (205) comprises a transistor (210) having a source connected to a bit line voltage (230) and a drain connected to an output voltage (225). The cascode amplifier circuit (205) also comprises a differential circuit (212) having an inverting input (215) connected to the bit line voltage (230), a non-inverting input connected to a reference voltage (202), and an output (280) connected to a gate of the first transistor (210). The operation of the transistor (210) and the differential circuit (212) generate a fast, stable the accurate bit line voltage (230).
