In this paper, an schema for controlling the oscillation frequency of a quadrature oscillator is proposed. The method involves controlling the threshold voltage of the PMOS transistors in the inverter through control of the bulk bias voltage. Results obtained using HSPICE simulation are presented in a technology of 0.35{\mu}m, and experimental results using discrete elements (HEF4007) are also shown. Both sets of experiments show the effectiveness of the technique., Comment: Conference DCIS'2007, paper 3B.1
