## Abstract A linear, lowβpower, wideband 0.18βΞΌm CMOS VCO for UWB applications is presented, as part of a PLLβbased direct FM modulator for the 3.1β5βGHz UWB band. It consists of a frequency control circuit and a differential ring core, coupled to the antenna output and the PLL prescaler by two si

## Abstract A 24βGHz powerβefficient pulse oscillator for ultrawideband (UWB) radar applications implemented with InGaP HBT MMIC technology is proposed. The oscillator uses a common base inductive feedback topology without output buffers. The bias current is switched on by a pulseβcontrol voltage.
## Abstract A CMOS wideband variable gain amplifier (VGA) with an exponential gain control characteristic is presented. The exponential gain control function is realized by changing the tail currents a differential gain stage. The bandwidth is extended by using an inductive peaking technique. The g
