Abstract
A circuit for minimizing variation over process, voltage and temperature for edge rate over and propagation delay. The circuit includes at least two first buffers for decoupling large nonlinear parasitic capacitors of the main drivers, at least two second buffers for level shifting to the at least two first buffers, at least two voltage sources for initializing the stage of at least one of the first or the second buffer, and a current source generator coupled to the voltage source of the second buffers.
