A variable frequency oscillator includes an inductance unit having a first inductance, a first variable capacitor coupled across the inductance unit, and a second variable capacitor coupled across a part of the inductance unit. The inductance of the part of the inductance unit coupled by the second variable capacitor is a proportion of the first inductance.

Highly linear-gain oscillator

A circuit for modulating an input signal including a dither signal generator configured to generate a first dither signal having a maximum amplitude, a deamplifier configured to reduce the amplitude of said input signal so as to generate a deamplified input signal having a maximum amplitude that is comparable to the maximum amplitude of the dither signal, and a summer configured to sum the dither signal with the deamplified input signal.
