Abstract
A signal generator includes a first voltage generator, a second voltage generator, an operational amplifier, and an oscillator. The first voltage generator generates a first voltage, and the second voltage generator generates a second voltage. The operational amplifier generates an amplified error signal based on the first voltage and the second voltage, and the oscillator generates a periodic signal based on the amplified error signal. The first voltage generator and the second voltage generator are configured to generate their respective voltages based on the periodic signal. As a result, frequency deviation in the periodic signal may be corrected, for example, without increasing the source current of the oscillator or the gain of the operational amplifier. Also, improved phase noise performance may also be achieved through an increase in loop gain.
