1. Design and Characterization of MMIC IF VGA and Small Signal CMOS Millimeter Wave Amplifiers
Abstract : The main aim of this work is to demonstrate the easibility of designing and characterizing monolithic microwave integrated circuit (MMIC) variable gain amplifiers (VGA) and small signal amplifiers in III-V (GaAs) and 90 nm CMOS technologies, respectively. The VGA is studied at the IFfrequency of 2. READ MORE

5. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers
Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE
