Abstract:
1. A circuit module, comprising: a plurality of phase-regulated circuits each being fed by an internal operating voltage corresponding to an individual reference voltage; a plurality of adjusting circuits, each adjusting a respective one of the individual reference voltages, each said individual reference voltage being generated by an individual setting device, using a trimmable internal master reference voltage; said trimmable internal master reference voltage representing a first one of the internal operating voltages; and said individual reference voltages each representing a further one of the internal operating voltages; said adjusting circuit including a comparator receiving the trimmable master reference voltage and one of the individual reference voltages, said comparator outputting a comparison result for setting one of the individual reference voltages; a circuit for generating one of the individual reference voltages, said circuit for generating the one of the individual reference voltages having a voltage setting input; a counter acting on said voltage setting input of said circuit for generating the one of the individual reference voltages; and said comparison result of said comparator being used to perform an operation selected from a group consisting of incrementing and decrementing said counter.
