Abstract
A feedback loop includes an oscillator-based analog-to-digital converter configured to convert an analog signal to a first digital value and a second digital value. The oscillator-based analog-to-digital converter includes a first oscillator having a first oscillation frequency configured to generate a first digital value based on a first signal component of the analog signal. The oscillator-based analog-to-digital converter includes a second oscillator having a second oscillation frequency configured to generate a second digital value based on a second signal component of the analog signal. The first and second signal components are complementary signal components. The feedback loop includes a combiner configured to generate a digital value based on the first digital value, the second digital value, and an offset code. The offset code has a value that increases a difference between the first oscillation frequency and the second oscillation frequency.
