Abstract :
This paper presents the performance characteristics of 14 GHz InP-based RTD MMIC voltage-controlled oscillators with the extremely low DC power consumption. In order to further reduce the DC power consumption of RTD based VCOs, RTDs with a small emitter size, such as 1.5 times 1 mum2 and 1 times 1 mum2 , are used for the negative resistance generator of the VCOs. Each VCO is implemented by using the same resonator and output buffer except the RTD size to investigate the performance of the VCOs with the variation of RTD size. The fabricated VCOs showed the sub-mW DC power consumption which is suitable for wireless sensor applications
