Abstract
A signal generator is disclosed that in one form employs an indirect digital-to-analog converter (DAC) assisted frequency synthesizer for switching a steering current into or out of a phase locked loop (PLL) filter capacitor. The signal generator provides fast switching performance and loop bandwidth adjustment to reduce phase noise and improve phase jitter performance. The signal generator comprises a channel signal selector, a digital-to-analog converter, a window generator circuit, a window comparator, a steering current circuit, a PLL circuit with voltage controlled oscillator (VCO), programmable divider, and a reference oscillator.
