Abstract
An application specific integrated circuit for use with a circuit having particular electrical characteristic such as ringing or impedance. The circuit has an output pad with an output transistor having a drain connected to the output pad, and a gate connected to the drain of a predriver transistor. The output transistor has a gate-source capacitance characteristic, and the predriver transistor has a predriver time constant above a selected threshold based on the electrical characteristic. The first predriver transistor also has a selected resistance based on the predriver time constant and the gate-source capacitance characteristic, such that the first predriver is operable to switch the output transistor at a sufficiently slow rate to avoid ringing.
