Abstract
Buffer circuits and techniques that reduce skew between rising and falling times of output data as process conditions vary are provided. One or more process-dependent current sources may be utilized to compensate for process variations by supplementing the current drive of transistors used to precharge (PMOS) or discharge (NMOS) an output node of a secondary (e.g., inverter) stage of the buffer circuit.
