We present a 31–45.5 GHz injection-locked frequency divider(ILFD) implemented in a standard 90-nm CMOS process. To reduce parasitic capacitance and increase the operating frequency, an NMOS-only cross-coupled pair is...
1.0μm gate-length GaAs-based MHEMTs have been fabricated by MBE epitaxial material and contact-mode lithography technology. Pt/Ti/Pt/Au and Ti/Pt/Au were evaporated to form gate metals. Excellent DC and RF performanc...
A monolithic voltage controlled oscillator (VCO) based on negative resistance principle is presented uti-lizing commercially available InGaP/GaAs hetero-junction bipolar transistor (HBT) technology. This VCO is de...
