<p>Apparatus are provided for voltage-controlled oscillators and related systems. An exemplary voltage-controlled oscillator includes a first variable capacitance element (120), a second variable capacitance element (122), and an inductive element (132) coupled between the variable capacitance elements (120, 122) to provide an inductance between the variable capacitance elements (120, 122) at an oscillation frequency of an oscillating signal at an output node (104). The first variable capacitance element (120) is coupled between a first control voltage node (110) and the output node (104), the second variable capacitance element (122) is coupled to the first control voltage node (110), and a second inductive element (134) is coupled between the second variable capacitance element (122) and a second control voltage node (112).</p> |
