Abstract
In this paper we present a fast automatic tuning algorithm for Voltage Controlled Oscillators (VCOs) with multiple tuning curves. Many practical implementation issues are shown along with their solutions. To evaluate the speed of the algorithm, a design example comprising a 2.4GHz VCO is presented where we use a regression test bench to run the algorithm many times each with a different initial VCO frequency and record the final VCO frequency and tuning time. The worst case tuning time is only 7.2μsec.
