Devices and methods for auto-tuning a tunable circuit based on a frequency of operation of the tunable circuit using a clocked frequency detector circuit are described. The clocked frequency detector uses a readily available clock signal to drive a counter circuit to provide an indication of the frequency of operation of the tunable circuit. The tunable circuit, including the clocked frequency detector, can be integrated within a same chip that is autonomously configurable based on the frequency of operation and the readily available clock.
