Common-mode feedback circuit

A differential amplifier circuit with common-mode feedback comprising:

• a first stage comprising a first differential input configured to drive a first differential pair transistor in a first differential current path, a second differential input configured to drive a second differential pair transistor in a second differential current path, a first differential output, and a second differential output;
• a second stage comprising a first differential input, a second differential input, a first differential output, and a second differential output;
• and
• a common-mode feedback circuit configured to continuously drive a first conducting element in a conductive state and a second conducting element in a conductive state, the first conducting element in a first common-mode feedback current path parallel to the first differential current path and comprising a first conducting terminal coupled to the first differential output of the first stage, the second conducting element in a second common-mode feedback current path parallel to the second differential current path and comprising a first conducting terminal coupled to the second differential output of the first stage.
