| Popis: | Design and implementation of a differential push-push voltage controlled oscillator (VCO), operating at 2.4 GHz, is presented in this paper.A presentation in space of thephase noise analysis and a graphical optimizationmethod are used to obtain the optimum phase noise of the differential push-push oscillatorwithrespectall design constraints. The proposed architecture isimplemented in the 0.25 µm BICMOS SiGe:C process of NXP Semiconductor. For only power dissipation 100mW, the proposed oscillatorgeneratesa phase noise of -131.5dBc/Hz @1MHz frequency offset at 2.4GHz with post layout simulation results. The core chip size is 1.6×1.1 mm2, with includingthe totality of the pads. |
