摘要： A dual differential sawtooth signal generator (106) includes a first sawtooth voltage generator (150) that has a first capacitor (178) and a second capacitor (196) that are alternately charged with a feedback control source current (IregP) from a low voltage reference voltage level (134, 182). A second sawtooth voltage generator (152) has a first discharge capacitor (278) and a second discharge capacitor (296) that are alternately discharged with a feedback control sink current (IregN) from a high voltage reference voltage level (126, 274). The output signals of the two sawtooth voltage generators (150, 158) are compared (108) to control a phase frequency comparator (110) that provides signals to control a dual charge pump (114) that provides the feedback control source current (IregP) and that provides the feedback control sink current (IregN).
