SENSE AMPLIFIER HAVING LOOP GAIN CONTROL

摘要

Memories, sense amplifiers, and methods for amplifying a current input are disclosed, including a sense amplifier including a bias circuit configured to provide a bias voltage having a magnitude responsive to maintaining a substantially constant loop gain, and further including an amplifier stage coupled to the bias circuit to receive the bias voltage and configured to amplify a input current at an input-output node, a loop gain of the current amplifier stage is controlled at least in part to the bias voltage.

主权项

1. A sense amplifier, comprising:
a sense amplifier stage configured to receive differential input signals and amplify the same, the sense amplifier stage including two modes of operation; and a mode control circuit coupled to the sense amplifier stage and configured to control the mode of the sense amplifier stage by adjusting a loop gain of the sense amplifier stage.
