Abstract
A CMOS Output Buffer providing controlled output impedance includes three internal sections each of which provides a impedance control for a corresponding region of the output V-I characteristics of deep linear, deep saturation and transition regions. Each internal section includes controlled current sinks/current sources enabled to provide a precise control over the DC impedance of the driver across the PAD voltage range.
