Abstract:
An LC sinusoidal oscillator comprising;(a) an inductive element connected to a supply voltage; (b) a capacitive element connected to an applied voltage, the oscillator to generate an oscillation frequency proportional to the applied voltage, said capacitive element further comprising: (i) a fixed capacitor circuit to determine the oscillation frequency; and (ii) a phase correction circuit comprising: (1) an incremental capacitive element connected in parallel to the fixed capacitor circuit, the incremental capacitive element comprising at least one field effect transistor whose gate is electrically connected to the capacitive element and whose source and drain are electrically connected to an incremental voltage source to change the state of the at least one field effect transistor to a depleted mode thereby decreasing the capacitance of the capacitive element and providing an instantaneous incremental frequency for phase alignment of the oscillation frequency; and (2) a decremental capacitive element connected in parallel to the fixed capacitor circuit; and (c) a negative resistance structure connected to the inductive element and capacitive element.
