An approach to estimate the distortion in CMOS short-channel (e.g. 0.18-/spl mu/m gate length) RF low-noise amplifiers (LNAs), based on Volterra's series, is presented. Compact and accurate frequency-dependent closed-form expressions describing the effects of the different transistor parameters on harmonic distortion are derived. For the first time, the(More)
This paper presents the design and experimental results of two CMOS low-voltage low noise amplifiers intended for future wireless applications, and featuring a new and very simple gain control mechanism. Implemented In a standard 0.18 /spl mu/m CMOS process, and operating from a supply voltage of 1 V, the 8 GHz LNA exhibits a power gain of 13.7 dB and a(More)
The design of two low power CMOS ultra-wideband (UWB) pulse-based transmitters is reported. The goal is to propose simple, low power, and tunable topologies for full-band and sub-band UWB transmitters. The first transmitter utilizes a gated ring oscillator, an NMOS switch, and a passive pulse shaping filter to generate a 3.1-10.6 GHz full-band UWB signal.(More)
