High power compact 16 GHz integrated oscillator design using active reactances

This paper reports on results obtained using an oscillator incorporating ac tive inductance and active capacitance concepts. The only passive reactance used is MIM capacitor. With the goal of high output power and low area con sumption, the analyzed circuit was realized in a 300 x 300 mum(2) compact a rea. A commercially available SiGe heterostructure bipolar transistor MMIC technology with relaxed lateral scaling of 1.2 mum has been used. This osci llator design provides a load independent oscillation condition provided by a cascode buffer stage. An output power of +12.5 dBm at 15.6 GHz is achiev ed. (C) 2001 Elsevier Science Ltd.
