摘要： A sawtooth voltage generator has a first capacitor that is charged with a variable feedback control current to provide a sawtooth output signal with a controlled amplitude. A feedback loop includes a comparator that compares a version of the sawtooth output signal with a fixed voltage reference to provide a comparator output signal to a phase frequency comparator, the output of which controls a source of the variable feedback control current. A method includes controlling the amplitude of a sawtooth output signal by charging a capacitor in a sawtooth voltage generator with a variable feedback control current; comparing a version of the sawtooth output signal with a fixed reference voltage to provide a comparator output signal; processing the comparator output signal in a phase frequency comparator to provide up/down control signals; and controlling the variable feedback control current with the up/down control signals from the phase frequency comparator.
