Low-Power Power Amplifier for 77-GHz Automotive Radars
نویسنده
چکیده
In this paper we present low-power 77-GHz power amplifier (PA) for the long range automotive radar. The proposed amplifier is designed using TSMC 0.13-μm RF CMOS (fT/fmax=120/140 GHz) technology, and it is powered by a 1.5V supply. To reduce power dissipation, we consider bias voltage, transistor size optimization, matchings and layout optimization. To improve power gain of the amplifier, it has a 2-stage cascode scheme. The proposed circuit showed the lowest power dissipation of 66.45 mW and the highest saturated power gain (Psat) of 23 dBm as compared to recently reported research results.

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
