Abstract :
A K-Band low phase noise voltage controlled oscillator (VCO) using balanced π-feedback with 1-um GaAs heterojunction bipolar transistor (HBT) process is reported in this paper. In this VCO, phase noise is -116.0 dBc/Hz at 1 MHz offset and tuning frequency is from 19.62 to 20.23 GHz. The differential outputs are also provided from the VCO due to the use of balanced π-feedback. The overall dc power consumption of the VCO is 90 mW with a supply voltage of 6 V.
