A 24 GHz Class-A amplifier is designed in 0.13um CMOS technology. The matching network for the cascode amplifier is implemented by microstrip lines that have been implemented in small space by meandering. The amplifier delivers 12.5 dBm power to a 50 Ω load from a 2 V supply. A maximum Power Added Efficiency (PAE) of 30% is achieved at 1-dB(More)
Electric field-enhanced emission of electrons from a deep level defect in GaN grown by hydride vapor phase epitaxy has been studied. Using the field dependent mode of conventional deep level transient spectroscopy ͑DLTS͒, several frequency scans were performed keeping applied electric field ͑12.8–31.4 MV/m͒ and sample temperature ͑300–360 K͒ constant.(More)
This paper presents the design of a single ended wideband LNA utilizing reactive elements at the input and output for impedance matching. It has been shown through simulations that the LNA architecture utilizes components similar to a narrowband design but achieves a much wider bandwidth with high gain and low noise figure. The single ended wideband LNA is(More)
