Abstract :
This paper describes the realisation of a high performance, low cost VCO. The VCO is tuneable over more than 100 MHz with an excellent phase noise. Some easy to implement optimisations will be given to improve the performance of negative resistance oscillators in general. Finally measurement results will presented
