Abstract
A driver circuit (12) having a controlled transition rate is provided. The driver circuit (12) includes a first device (56) operable to switch a supply voltage to load. A second device (54) is coupled to an input for the first device (56) in source follower arrangement. A third device (66), coupled to the input for first device (56) and an output for the second device (54), is operable to function as a Miller amplifier in conjunction with the first device (56). A fourth device (152) is coupled to an input of the second device (54). The fourth device (152) is operable to function as a Miller amplifier in conjunction with the first device (56) and the second device (54). A capacitor (68) is coupled between an output for the first device (56) and inputs for the third device (66) and the fourth device (152). The capacitor (68) is operable to function as a Miller capacitor to control transition rates at the output of the first device (56).
