ABSTRACT:
A high-performance, low energy amplifier circuit for the detection and amplification of a voltage differential includes a current conveyor and a sense amplifier. The current conveyor includes a pair of cross-linked transistors and a pair of pass transistors. The sense amplifier includes four transistors forming a cross-linked current sense amplifier. The current sense amplifier detects a current differential between complementary bit lines, develops a differential voltage based on the current differential, amplifies the differential voltage and outputs the amplified differential voltage.
