Methods, systems and apparatuses for operating a converter or other circuits are disclosed. More particularly, in one embodiment a converter or other circuit can be operated in two modes which may include the count-to-time and time-to count modes to determine an output value corresponding to an input signal. During operation in the count-to-time mode a converter may be operated using a reference signal to determine a number of clock cycles needed until an output corresponds to a scaling factor is reached. During operation of the circuit in the time-to-count mode then, the converter may be operated for this number of clock cycles using the input signal to determine an output. This output may be proportional to the level on the input signal.
