Abstract
A process friendly precision voltage generator for use in a digital/analog system or the like, includes a modified phase lock loop (MPLL) and a frequency control system for adjusting the frequency of the MPLL until a desired reference voltage is obtained at an output node of the loop filter. The frequency of the phase lock loop is then locked to the frequency, at which the desired reference voltage has been obtained.
