Abstract:
An amplifier includes a differential input stage, a hysteresis stage, coupled to the differential input stage, a cascode stage coupled to the hysteresis stage, a feedback stage coupled to an output of the cascode stage and configured to provide a feedback signal to the hysteresis stage, and an output stage coupled to the output of the cascode stage. The output stage includes a hysteresis inverter coupled between the output of the cascode stage and the amplifier output.

Claim (Index 12):
An amplifier comprising:\n an output stage configured to provide an amplifier output; an input stage having a differential pair of transistors, wherein a control electrode of a first transistor of the differential pair is coupled to a non-inverting input of the amplifier and a control electrode of a second transistor is coupled to an inverting input of the amplifier, wherein the amplifier output switches states in response to a voltage differential between the inverting input and the non-inverting input; a hysteresis stage coupled to the input stage; a cascode stage coupled to the hysteresis stage, wherein the hysteresis stage is configured to provide hysteresis to an output of the cascode stage, wherein the output stage is coupled to the output of the cascode stage and includes a hysteresis inverter coupled between the output of the cascode stage and the amplifier output; and a feedback stage coupled to the output of the cascode stage and configured to provide a first feedback signal and a second feedback signal to the hysteresis stage; wherein the hysteresis stage further comprises:\n a second pair of differential transistors including:\n a third transistor including a control electrode coupled to receive the first feedback signal; and \n a fourth transistor including a control electrode coupled to receive the second feedback signal; \n \n wherein the first transistor is configured to control a first current at a first node of the cascode stage, and the second transistor is configured to control a second current at a second node of the cascode stage, wherein the third transistor is configured to control a third current at the first node of the cascode stage, and the fourth transistor is configured to control a fourth current at the second node of the cascode stage; wherein the hysteresis provided by the hysteresis stage is dependent upon the third current at the first node and the fourth current at the second node; wherein the amplifier further comprises a current control circuit coupled between a supply terminal and the second pair of differential transistors to control current between the second pair of differential transistors and the supply terminal, the current control circuit including an input coupled to a node configured to provide a common mode voltage of the inverting input and the non-inverting input.
