Method, system and apparatus for dual mode operation of a converter

摘要

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.

主权项

1. A converter, comprising:
a converter configured to operate using an input signal for a number of cycles of a clock to determine an output count, wherein the number of cycles is substantially equal to a clock count and the clock count was determined during a calibration process using a desired scaling factor.
