Abstract
This disclosure provides examples of circuits, devices, systems, and methods for providing high speed operation and a high noise margin. In one implementation, a circuit includes a first buffer configured to receive an incoming signal and a control signal and to generate an output signal based on the incoming signal. The first buffer exhibits a first hysteresis range while configured in a first hysteresis state and a second hysteresis range while configured in a second hysteresis state. The first buffer is configured to transition from the first to the second hysteresis state and vice versa in response to the control signal. The circuit includes a second buffer configured to receive the incoming signal and to generate the control signal based on the incoming signal. The second buffer exhibits a third hysteresis range with a lower threshold and an upper threshold.
