Abstract :
An original method to increase the tuning range of a MMIC varactor diode is presented. An active circuit simulating a negative capacitance is connected to the varactor diode. This method allows to increase the varactor´s tuning range more than ten times. A MMIC simulating a negative capacitance have been successfully fabricated and measured and we hope to be able to present measured results of a complete active varactor by the time of the symposium.
