Abstract: PURPOSE: A quadrature-phase voltage controlled oscillator is provided to reduce area consumption by forming a structure of using one transformer without using individual inductors. CONSTITUTION: A first voltage controlled oscillator(110) is connected between a power terminal and a first bias terminal to generate first and second oscillation signals. A second voltage controlled oscillator(120) is connected between the power terminal and a second bias terminal to generate third and fourth oscillation signals having 90° phase difference in the first and second oscillation signals. The first and second voltage controlled oscillators can be formed into the same configuration. A biasing transformer(130) connects the first voltage controlled oscillator and the second voltage controlled oscillator to a ground terminal. The biasing transformer is connected between the first bias terminal and the ground terminal of the first voltage controlled oscillator. The biasing transformer is connected between the second bias terminal and the ground terminal of the second voltage controlled oscillator.
