ABSTRACT:
A frequency response adjuster for a frequency responsive circuit, and a method for tuning a frequency response of a circuit, are disclosed. The adjuster may include a time constant sensor, wherein a charging state of the frequency responsive circuit may be measured by, and output from, the time constant sensor as a first voltage, a converter that samples the first voltage and outputs a second voltage resultant from a conversion of the first voltage by the converter, an array of trimming components, and a selector that utilizes the second voltage to select at least one trimming component from the array of trimming components. The method includes the steps of sensing a time constant of the circuit, outputting the sensing as a first voltage, sampling the first voltage over a fixed interval, converting the sampled first voltage to a second voltage, and selecting, utilizing the second voltage, at least one trimming component from an array of trimming components. The time constant of the circuit may be trimmed by the at least one trimming component selected.
