Abstract
An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate an output signal that ramps between a first and second frequency in response to (i) a first control signal, (ii) a second control signal, and (iii) a first reference signal. The second circuit may be configured to generate the first and second control signals in response to a third control signal having a third frequency. The third frequency may reduce electromagnetic interference generated by the first circuit.
