A novel approach to frequency dividers based on the nonlinear feedback control of MESFET in forced oscillation mode is proposed. The input signal is used to control the FET gain, imposing oscillation conditions. This approach is first tested by time-domain simulation. An experimental MESFET analog frequency divider exhibits high gain conversion and low threshold input power values. The good agreement between simulated and experimental results confirms the proposed models and concept.<>
