Abstract
Methods and systems of generating a frequency switching local oscillator signal are disclosed. One method includes generating a reference clock signal, and clocking a counter with the reference clock signal. The counter controls selection of a one of a plurality of analog values stored in at least one of a plurality of periodic signal generators. The frequency switching local oscillator signal is generated by selecting an output of a one of the plurality of periodic signal generators.

A method of generating a frequency switching local oscillator signal, comprising:
- generating a reference clock signal;
- clocking a counter with the reference clock signal;
- the counter controlling cyclical selection of a one of a plurality of analog values stored in a periodic signal generator, the cyclical selection producing a periodic signal at an output of the periodic signal generator;
- controlling a frequency of the periodic signal at the output of the periodic signal generator by controlling an order of the cyclical selection of the plurality of analog values stored in the periodic signal generator;
- generating the frequency switching local oscillator signal based on the periodic signal.
