    摘要： A voltage-controlled oscillator has a tuned circuit for controlling the oscillation frequency. The tuned circuit has a variable-capacitance element whose capacitance varies in response to a control voltage and a negative capacitance circuit whose impedance frequency characteristics have opposite characteristics to those of a normal capacitance, and which is connected to the variable-capacitance element. The configuration enables increasing the variation ratio corresponding to the control voltage of the combined capacitance composed of the variable-capacitance element and negative capacitance circuit, thereby broadening the oscillation frequency band.
