Abstract
A system comprises an oscillator circuit that includes first and second tuning banks and a current-controlled oscillator. The first tuning bank is connected to a voltage node and receives the tuning signal, generates a voltage drop at the voltage node that corresponds to the tuning signal, and allows the flow of a first current therethrough that varies with the voltage drop. The second tuning bank is connected to the voltage node and receives an oscillator input signal and regulates a second current that flows therethrough in response to a voltage difference between the voltage drop and the oscillator input signal. The current-controlled oscillator receives a third current that is a sum of the first and second currents and fine-tunes an oscillator output signal based on the third current to track a frequency of a reference input signal.
