Variable gain amplifiers (VGAs) or a voltage controlled amplifiers are signal-conditioning electronic amplifiers that vary its gain depending on a control voltage. They are utilized in various applications of remote sensing and communication equipment. Applications of VGAs include radar, ultrasound, wireless communication, and even speech analysis. These applications use VGA mainly to enhance dynamic performance. The idea behind this work is to reduce the number of road accidents by developing in the automotive radar fields multichannel sensor systems which give 3D vision to the car so that the driver is able to detect collisions. These sensor systems employ receivers having variable gain amplifiers (VGAs) as one component of the receiver chain. In this work, the design of variable gain amplifier for automotive radar applications has been implemented taking into account linearity, noise and gain trade-offs.
