Abstract
An input signal is routed to a first logic one reference signal generator or alternatively routed to a second logic one reference signal generator based at least one a voltage level of the input signal. When the voltage level of the input signal is less than a threshold value, the first logic one reference signal generator selectively generates a first logic one reference signal. When the voltage level of the input signal is greater than or equal to the threshold value, the second logic one reference signal generator alternatively generates a second logic one reference signal. The first and second logic one reference signals may be used to control a first voltage scaling circuit that drives a scaled output signal having a logic one value corresponding to the voltage level of the first logic one reference signal.
