Abstract
In this work, a 300-GHz fundamental-mode differential Colpitts voltage-controlled oscillator (VCO) has been developed based on a 250-nm InP HBT technology. All inductive components are realized with inverted transmission lines while varactors are implemented by HBTs with base and emitter tied together. The VCO exhibits a frequency tuning range of 294.6 GHz to 301.7 GHz with a maximum output power of -1.9 dBm. The total DC power consumption is 59.8 mW. The circuit size including pads is 460 µm × 675 µm. Imaging was successfully demonstrated with the developed VCO used as the signal source.
