摘要
A phase locked loop (PLL) based frequency sweep generator and methods for performing a frequency sweep are disclosed. In one implementation, the frequency sweep generator includes a circuit configured to generate a signal having a saw-tooth wave frequency ramp. The saw-tooth wave frequency ramp includes a rising portion and a resetting portion. The resetting portion has a shorter duration than the rising portion and includes a plurality of steps for decrementing the frequency of the signal.
