Abstract :
The design of two fully integrated 43-GHz voltage-controlled oscillators (VCOs) implemented in a 90-nm CMOS process is presented. Both use standing-wave transmission line resonators instead of a lumped tank to provide extended output frequency ranges and relatively low phase noise (PN). Coplanar waveguide structures with and without slow-wave features were employed in the two VCO circuits. The test results of the manufactured chips were compared. The circuit with the slow-wave feature showed a lower PN (-102.7 dBc/Hz at 1 MHz), whereas the one without the slow-wave structure showed a wider tuning range (1.96 GHz). The two VCOs were developed for use in licensed E-band transceiver systems.
