Abstract:
An apparatus includes a load pair including a first transistor and a second transistor, a common mode feedback circuit comprising a first common mode feedback transistor and a second common mode feedback transistor, wherein a drain of the first common mode feedback transistor is coupled to a source of the first transistor, and a gate of the first common mode feedback transistor is coupled to a drain of the first transistor, and a drain of the second common mode feedback transistor is coupled to a source of the second transistor, and a gate of the second common mode feedback transistor is coupled to a drain of the second transistor, and an offset cancellation stage coupled to outputs of the load pair.
